Q:I am planning to buy a big guitar amp from america and you dont want to mess around with something as powerful as that so i want to know is there suitable adapters out there for such a job? because i heard that some electrical equipment from America will eventually burn out if you use it in Ireland!!help!?!?!

As long as you get a proper adapter that can handle the load, you should be fine

Q:I am assuming that the car is running when the items are being used.

Car is running? No sweat!

Q:Curiosity just got the best of me. To be electrocuted one should make a complete circuit, right? What if you just touch the live wire and nothing else, you're not standing on anything, no ground. you're in mid air. Any thoughts? Thanks

No. Your comment about a complete circuit is correct. Under the conditions you state you will not be electrocuted. One exception would be if the line frequency and voltage was high and you had substantial capacitance to ground you might be electrocuted.

Q:2)Please do include the details as to why does spark devlop wn connection at one end is loose. 3)How the +ve electrode retains itz polarity though it accepts the electrons continuously, in a closed circuit.

1) For laymen understanding, electrical grounding is a protection of your house against lightning, instead burning your house or someone inside your house gets fried. In your appliances, electrical grounding protects you from getting electrical shock in case one of the electrical wire touches the metal body of your appliance. Now on electronic grounding, it is a protection of a certain circuitry from getting damaged by an electrical charge from your body in case you touch it. 2) Electrical wire connection is like a water pipe connection. Electrical current passes through the wire while water current passes through the pipes. If there is a loose connection of a certain electrical wire, or loose pipe connections on your water pipes; The loose pipe connections will produce leaks while the loose electrical connections will produce sparks. 3) It always retain its polarity always. Just like magnets, it retains its polarity, north and south. Electricity is based on magnetism. Law of nature.

Q:i replaced my home theater system thinking it was busted but when i recieved my new one it still had the same buzzing sound i noticed the buzz is in the bedroom too

It sounds like somewhere in your electrical you either have a bad ground, or there is a florescent lamp or some other piece of electrical equipment causing the noise. Surge protectors will only help with an electrical surge, a power conditioned is what is used to remove noise from electrical lines. Check the different electrical equipment in the house by turning things off or unplugging them and check if the noise goes away, if not it could be in your electrical system or some kind of outside interference. If you still issues purchase a surgex power conditioner and that should take care of your issue.

Q:Hey, I need to find out different electrical equipment used in a Beauty Salon and I can hardly think of anything! I can only think of wax pots and tanning beds :S Any other suggestions? Actual answers only please, don't bother writing Do your own homework or whatever because I really can't be bothered with people like that. Like I said I have TRYED and I cannot think of alot. Thankyou :)

Those blow dryers you sit under, and also those little dryers used to dry your nails when you get them done.

Q:how we can design the power rating of any electrical equipment. as per my understanding only way is is to change the resistance of coil( winding if motor, filament if lamp).if it is correct then the equipment will be burn if resistance is low for low power rating. Eg. resistance of filament of 10 w lamp is lower than the resistance of 100 w. generally life of 10 w lamp is higher than 100 w. but in electrical point of view the life of high value of resistance equipment will be higher than the low value value of resistance. means, 10w bulb will glow longer time comparatively 100 w bulb. since 10 w bulb has high resistance , so this bulb's life should be higher than 100w bulb. can anyone explain how to design the power rating of any electrical equipment in line of other electrical parameters.

The power rating of most power components and devices is limited by thermal considerations, since the life of them is a strong function of temperature. A rule of thumb is that for each 10 degrees C increase in temperature the life is cut in half.

Q:I have a piece of electrical equipment at a voltage potential of 277VAC to ground. Due to hardware problems I have an air gap of 3/8 from ground to 277VAC when it used to be one inch. Please advise if I am safe to leave it that way or should I add insulation.

That is ok with respect to any possible arc. But there may be other reasons to add insulation. Safety for example. If it's easy to add the insulation, do it. .

Q:EMP is a byproduct of a nuclear explosion. It can cook solid state electronics and computers. The great danger is that nuclear air bursts can take down the computers that manage our banking, our record-keeping, and even the ones that manage our automobiles.The military services have taken some steps to protect their electronic systems from EMP, mainly by shielding. However few of our civilian electronic systems are protected in any way from this threat.Obviously there are two ways to deal with it right now. One is to prevent the explosion by deterring a nuclear attack. The other is to find some way to protect our senstive electronics.What should we do, and what can we do starting today?

On a personal level: Buy a car made before 1973. With no computer parts, an EMP would not have any effect. Get a radio and TV that uses the old vacuum tubes. They are not effected by an EMP. And NEVER EVER get a heart pacemaker. If you got one of those, you are toast.

Q:Hi I'm doing a music project at the moment, writing songs, music, etc.my genre would probably be considered alternative/electronic rockMy current vision for my set up is an electric guitar and my macbook.I create most of the music via macbook (drum parts, synth parts, basically all the programing)Playing live i suppose i'd play these songs on my laptop. While i do this, i sing, and play rhythm guitar along with the samples and instrumentals on the macbook.My question is, how do I connect all this stuff on stage? Could anyone out there recommend anything that I could use to connect my macbook to speakers for performing live.p.s I know nothing of playing with electrical equipment (been doing acoustic for a very long time) all I know about live equipment is connecting a guitar to a guitar amp.so is there like a way to connect a macbook to an amp? or speaker of some sort?Thanks in advance.

In order to get the most from your Mac as sound generator use a reasonably good audio interface (like the E-mu 0404 usb or something from M-audio). This should be connected to a mixer and this one to the PA system. You also should connect your microphone and guitars to the mixer too, so you can control the volume of each instrument, including the Mac. Although you can connect the mac directly to an Amp I won't do that in order to get control of volume and have better sound. Computers generally don't like live performing. Electric voltage can be unstable (heavy power consumption and lights on-off pattern). Use the appropriate electric equipment to make sure the computer always receive the correct amount of voltage. If not, it can fail and ruin your performance. Make a test where possible.
