Q:High school physics, according to the transformer U1 / U2 = N1 / N2 Can make a large voltage into a small voltage, but the small voltage can become a large voltage? Need no conditions? Can the transformer be used only for alternating current? I am now only high school physical level, answer not too esoteric or too professional! Thank you !!

Small voltage can become large voltage. If only in the theoretical considerations, as long as meet the N1 <N2, you can make U1 <U2.

Q:i have a bunch of transformers and they have the dates like i have optimus prime it says takara hasbro 1980-1982 and all the other toys say hasbro or takara! and most are made from 1982 -1985 also i have jet fire but the stamp doesn't say hasbro or takara but it does say bandai 1984!

this is defined in the action picture, which occurs between Season 2 and Season 3. additionally, word that new characters ensue in particularly some episodes devoid of rationalization, and not in easy terms in Season 3.

Q:I have 14 gauge wire and some 28 gauge wire. Do both lengths of wire have to be insulated? Is it as easy as winding the 14gauge wire top to bottom and then do the 28 gauge wire top to bottom also? I'm guessing this is a step up transformer because the battery is going through the 14 gauge wire and then the lightbulb is hooked to the 28 gauge wire?Does the direction on winding matter at all? Say, CW for the 14g and then CW with the 28 gauge?

ferrite rods are not customarily used for transformers. at RF they are sometimes used as a core for a loop antenna. your application sounds like an ignition coil as you need an interrupter on the DC input (like points on a car ignition). the primary wire (14 gauge) would just be a few turns and not likely to run the full length top to bottom, the secondary (28 gauge) would be a lot of turns like 10 or 20 times as many. direction of winding would not matter in this application as capacitive coupling between the windings should be insignificant. all wire has to be insulated as a shorted turn spoils the transformer effect. wire used for transformers is customarily insulated with lacquer as plastic adds too much bulk to make tight windings. if you already have bare wire, then you made have some success by dipping the wire in lacquer paint first. it sounds like you are duplicating a project you have seen elsewhere. without knowing the source, it is hard for us to guess what the circuit parameters need to be for the transformer. but as i pointed out initially, i am skeptical that you will get this to function in the manner you are expecting. AC power transformers of the kind that use these wire gauges always use a torroidal core ferrite, never a rod. static DC cannot be transformed at all.

Q:Can a european power outlet handle a 5000 watt power transformer?

A Power Transformer is usually rated in KVA, or Killo-Volt Amps. Hard to answer your question without the right info on the size of the X-fmr, What it is being used for, and the number of taps on said X-fmr. An appliance that consumes 5K Watts of power can be translated to about 7 Amps @ about 100 to 120 Volts A.C. It can also be translated to about 3.5 Amps @ 200 to 240 Volts A.C. I like to over rate things in my calculations, for safety sake. That way, there are no accidents in adding up figures wich could possibly cause a circuit overload. Frequency of the line doesn't really matter, unless you are converting power for an imported or domestic unit, whatever the case may be. Consult your local friendly electrician for other details.

Q:i can't seem to think of the name or artists of this song. All I could remember it has transformer lyrics (not the theme song). it has an old school hip hop/rap vibe to it but i need help of what's the name of it, thanks!!!

Q:How do step up transformers obey the law of conservation of energy?

I often end up submitting the same question on other sites

Q:Can anyone explain what each wire does in this spicific microwave transformer

The bottom coil with the 2 tabs is the primary. The 2 red wires leading off to the right is a low voltage secondary with high voltage insulation so that they remain isolated from the other windings. It powers the filament of the microwave tube. The other red wire leading off to the left is one end of the high voltage secondary. It normally connects to a high voltage rectifier and capacitor and then to the cathode of the tube via one of the filament connections. You can expect to see negative pulses in the 2000-3000 volt range at that connection with an available current that is several times the lethal level. The other end of the high voltage secondary is grounded to the frame of the transformer at the rivet at the top center. The anode (plate) of the tube is also grounded through its mounting hardware. Most microwave transformers run hot even when lightly loaded since they are run fairly close to saturation on the B-H magnetization curve. You'll need a fan if you are using it for extended periods. If you carefully remove both secondaries and the steel magnetic shunts wedged in between the primary and secondary windings, you'll have the foundation for winding your own transformer good for about 400-600 watts. First add about 10 more turns to the primary which will cut the core losses significantly by running it lower on the curve. Expect to see about 1 volt per turn on any new secondaries you wind. Don

Q:Rectifier and rectifier transformer

First of all to clear their own concepts to distinguish. 1. Transformers, Narrow concept: the concept of power transformers is able to electromagnetic coupling by a certain type of alternating energy into another standard alternating energy, such as voltage and current conversion, but in any case, the energy is conserved; General concept: any equipment capable of transforming can be a transformer; for example, switching power supply, resistance step-down, three-terminal regulator, and so on; 2. Rectifier, Rectification is the process of turning the alternating signal into a DC signal. The rectifier is a device that can turn the alternating signal into a DC signal. 3. Then look at the difference, Rectifier as mentioned above, the AC signal into a DC signal; For example, you can use a rectifier (rectifier bridge) to convert the mains 220V 50Hz AC into 308V DC; Rectifier transformers, that is, in the "AC into DC" can also be voltage conversion, for example, can be reduced after the rectification of 308V into 5V, 9V, 12V, or boost into 400V, 450V, 500V, or other you Want the voltage. Of course, here the transformer to do a broad understanding, because your voltage has been rectified DC voltage.

Q:I realize this may be super simple but i cant for the life of me figure out how to open a wall mount transformer it seems like they are snapped shut with no way to open?

They are glued, or even sonically welded. They are made to be replaced not repaired. They can be open by sawing a knotch in the corner and prying open with a screwdriver.
