Q:come on.the battle scenes and all the transformers were totally awesomebut.all the small jokes that sam and his parents and other various characters madejust killed itlike they were actually trying to add a comic element to it.and what is with the transformers cussing? it doesnt feel righttransformers dont cuss.lol

I concur. Transformers 2 had some really awesome cinematography, most notably the battle sequences, but it really wasn't worth the praise. The jokes felt too forced, the film felt rushed, and the acting was terrible. It wasn't awful like critics are saying, but I wouldn't really watch it again. The first Transformers was better because the jokes didn't feel too forced and the film didn't feel really corny like its follow-up.

Q:For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?

You are right. The value of a coil is measured in Henries and is determined by number of turns, size of wire, type of wire (commonly copper or aluminum). That is the reason you should not leave adapters and chargers plugged in. When not in use they should always be un plugged from power source.

Q:I bought a Neon Sign Transformer over OKorder and for a while it worked great. I used it to power a Jacobs Ladder (I wired the transformer straight to the Jacobs ladder). However, now the transformer will turn on the jacobs ladder but after a couple of seconds it will shut off and sometimes make a buzzing noise. What is wrong with it and how can I fix it?

It sounds like your transformer is shot and your chances of repairing it are pretty low. You may have been overloading it and burnt an internal connection. Do you have access to a good ohmmeter? Check the resistance, L1 to L2 and H1 to H2, preferably when it's warm like right after it's stopped working. The high side should be several times higher than the line side. Unless you are really sure you know what you are doing don't even try to repair it. The high side is putting out 8 to 10 KV and if your repair isn't up to it you can bet it will leave a mark.

Q:What is the meaning of the transformer 'turns ratio'? what's the effect?

The number of turns of the primary coil (that is, the number of turns around the coil) and the number of secondary turns. Turns ratio and voltage ratio is proportional. For example, 220 volts to 10 volts voltage ratio is 220: 10, turns ratio should also be 220: 10, such as the primary is 2200 laps, the secondary should be 100 laps. Multi-turn ratio is the number of turns of the secondary output and the primary correspondence. A variety of turns ratio is to allow a sensor device is used for a variety of heat treatment process. I remember answering your question? how? Do not believe? 'U1 / U2 = n1 / n2' "/" Or ":" read here as "than", the size of the ratio is that you say the size of the divisor, you put it when the division can also be seen. U1 / U2 = n1 / n2 'U1 denotes the primary voltage of the transformer, U2 denotes the secondary voltage of the transformer, n1 denotes the number of primary turns of the transformer, that is, the number of turns, n2 denotes the secondary turns of the transformer, The number of turns, n1 / n2 is the turns ratio. The meaning of this formula is: transformer primary and secondary voltage ratio = its primary and secondary turns ratio (turns ratio) I do not know you can not understand, do not understand I can do nothing

Q:Here's photos of the transformer in question. My dad pulled it put of some electronic he can't remember what and has had it sitting on the garage. Recently I've been working with high voltage and he pulled this out for me to work with just having trouble figuring it out

First of all, never assume anything! There are some standard colour codes for transformer wiring, but not all transformers conform to the standards. In practice, a manufacturer can use any colour wire for any purpose, leaving you and me and a lot of other people wondering for all time, which wire is which? The measured DC resistance does not tell you anything about the AC voltage rating of any winding. With most power transformers, if there are two solid-black wires, they are the primary. If it is tapped, or there are two primaries (such as in dual-voltage units), there will be three or more primary wires (and possibly as many as 8!). I think the side with 115V on it is probably -- mind you, this is not for certain -- nothing more than the side on which that number happened to be stamped. So of course you want to know what to do next. Considering the number of wires and the ways in which they are connected, it would seem that an experimental method will be required. The 2006 ARRL Amateur Radio Handbook (and possibly other editions) tells how to figure out what's what with transformers. I strongly recommend using the procedures described therein.

Q:Hi there.I have purchased a Stepdown Transformer so i can use a Record Cleaning Machine I am buying from the U.S.It uses a powered suction unit to clean the record.All transformers for use with American equipment have 110v output, but i think your equipment is usually 120v.in I have been told that there is nothing to worry about as 110v out on the transformer is enough to power the equipment connected to it .Our AC output in Australia is 240v but we can use any voltage from 220 to 250. Therefore 110v should be enough.can anyone clarify and tell me it should be ok.Thanks a lot in advance.

I live in New Zealand. We use 240v 50Hz mains here too. USA uses 110/115v 60Hz. There is a 10Hz voltage frequency difference as well as the voltage difference. The stepdown transformer will be rated for 110v RMS(root-mean-squared). This is a kind of average, for want of a better description. The peak voltage is 0.707 times the RMS voltage. This is the peak on one half of the sine-wave(180'), therefore the complete sine-wave mains frequency represents 1.414 times the RMS voltage.(360' sine-wave cycle) Multiply 110v by 1.414, and you will get the peak-voltage, which is the maximum that the AC voltage can swing, both in the positive and negative parts of the sine-wave. 110v example: 110 x 1.414 155, therefore, the PEAK voltage for the States is 155v AC, or thereabouts. 240v example: 240 x 1.414 339, therefore, the PEAK voltage for Aus/NZ is 339v AC, or thereabouts. All mains voltages are a measure of averages(RMS), so a 10 or so volts either side of the stated voltage, should not prove to be a problem. Provided that the stepdown transformer can supply at least a few amps of current on the secondary(the 110v side), there will be no problems at all. Technically, the 10Hz frequency difference can make a slight difference, especially if you are trying to power some sound equipment from the States, as the Australian/New Zealand 50Hz frequency will mean that the motor will run slightly slower then the designed RPM. However, in your case, I don't think it will make one iota of difference. :)

Q:I have a nice little 120VAC to 7.5KV transformer that used to call an air purifier its home, but I'm not sure how to wire it. I have some guesses, but I want to make sure I don't burn down my house so I am hoping to verify them with the help of the yahoo answers community.

Do you have a volt/ohm meter? If you do, with the transformer unplugged from any AC source, take the ohm meter and measure the amount of resistance in the black/white AC input leads; then see if there's continuity between those wires and the long white wire coming off the same side of the transformer as the AC input leads. Then take the ohm meter and measure the resistance between the single output lead and the green wire. Also check to see if there is a meter reading between the output lead and the AC input wires. If there's readings between all transformer wires, you probable have what is called an Auto-transformer. The output is tapped from one secondary winding common to both AC input and HV output. Did you take the manufacture name and model number off the transformer and do an Internet search to see if there might be an online circuit diagram? ------------------ If all else fails, make sure that all the wires from the transformer are not accidentally touching or anything and that they are situated well apart from one another, then hook up AC voltage into the transformer. Don't attempt to measure any voltages with your meter. Most likely it will not read voltage that high. Be very careful, the voltages on that transformer can HURT YOU seriously. Do not fool with the transformer leads with AC voltage applied to it. Plug in the AC voltage and observe the transformer. If nothing starts popping and smoking, it probably functining alright. Unplug the AC from the transformer. Even if the transformer was defective and shorted out internally, all it would do is cause a circuit breaker in your house to kick off. Simple matter of disconnecting the AC from the transformer and then reseting the circuit breaker. Be careful. That thing isn't a toy, and if you don't understand what your doing, that thing will hurt you or worse.

Q:For a project, I need a sine wave with an RMS amplitude of 1000 V at least.I have a function generator that only makes sine waves at most of 7 V RMS.I have a neon transformer w/ a 120 V primary and a 3,300 V secondary and a step down transformer w/ a 120 V primary and 16 V secondary, which is used backwards.Well, I can only get 585 V max. I decided to get some low power step down transformers (Hammond Mfg. 162 series) w/ dual primary and secondary windings. so I can try different combination of step up.I thought the smaller the core would be less of a load for the generator. I get 30 V out of the HVAC tran. (10 VA rating) when the big transformer is hooked up, but for a Hammond w/ a similar winding ratio and (1.1 VA) w/ a similar winding ratio, but I can only get like very little out of the big transformer when hooked up.Is there another factor. I read something about transformer impedance, I was thinking of doing a quick measurement of that on them.

You are confusing VA (power ratings) with transformer ratios 120/16 7.5 :1 3300/120 27.5 : 1 So connect 7Vrms to 16 input to give output 1 52.5V Now connect this 120 (52.5V) output to the 120V input of the 120/3300 transformer The output should be approx 52.5 x 27.5 1444 Volts Use the 16/120 to step up and then the 120/3300 to step up again Take the function generator voltage to its lowest and measure at all points now gradually increase the generator voltage measuring at all points until you get what you want If the voltages are not as you expect then the VA ratings may be a problem Remember to be extra careful with High Voltages

Q:Here we go I have 4 transformers (230V to 12V) and 4 radio receivers. I have one transformer connected to one receiver. Similarly all transformers are connected in the same way. Now, I used a connection box (normal heavy duty ones bought at hardware shop-i think its made of some kinda fibre) to house 2 transformers and 2 receivers. This scenario is happening in my roof. I went to open one of the box the other and the transformer was hot. It wasn't hot to the point of not being able to hold it. But hot enough for me to hold it for for a while before letting go. So the basics here is that one transformer is only powering one receiver which is OK for the load. But I am a bit worried as to whether this can start a fire in the roof. Any advice please? Can this scenario lead to a fire? (Even though there is no overloading)

Pete's answer is a winner. The only thing I'd add to it is that all electronics that generate heat must be vented. You didn't say you had any venting. Sometimes that venting can be convective current venting (hot air rises, cool air enters from below) OR can be a cooling fan. Like Pete said, without specs and loads we can't tell for sure if there's a danger. And until you KNOW there is no danger, assume there is. Hope this helped. '')

Q:Hi. I love the music from the movie Transformers, but none of its in the soundtrack I like the theatrical music played throughout the movie. Its all instrumental and there are no words, very good stuff. I thought it might be Hanz Zimmer who did it but I cant find out if it is him or not and how to get the music. The soundtrack bellow is not the one im looking for.1. What I've Done - Linkin Park2. Doomsday Clock - Smashing Pumpkins3. This Moment - Disturbed4. Before It's Too Late (Sam And Mikaela's Theme) - Goo Goo Dolls5. Pretty Handsome Alukward - The Used6. Passion's Killing Floor - HIM7. What's It Feel Like To Be A Ghost? - Taking Back Sunday8. Second To None - Styles Of Beyond Featuring Mike Shinoda9. End Of The World - Armor For Sleep10. Retina And The Sky - Idiot Pilot11. Technical Difficulties - Julien-K12. Transformers Theme - MuteMath Just the instrumental work done in the movie. If u know who or where I can or might get it, I greatly appreciate it.

i detect that lots of the time I do savor the songs/albums I finally end up loving maximum on the commencing up pay attention, just to no longer the full quantity. those that should advance on me thoroughly are not as undemanding. The songs i'm maximum accustomed to are classic rock radio standards i've got been listening to because of the fact in the past i can submit to in suggestions. i've got listened to them maximum of cases without getting unwell of them. whether i'm previous the degree of being obsessed on those songs, I nevertheless discover those songs the main common to savor. Being very accustomed to a music makes it like a convenience nutrition and quite enables my appreciation of it. even although, i would not say I inevitably choose that familiarity to get exhilaration from some thing. Familiarity purely has a tendency to weed out the catchy songs that lack actual substance. i've got no longer at as quickly as theory approximately this in the past, so I make an apology for that jumble.
