Can you use 120V lamps in Europe by just putting in a 240V bulb and a European adapter on the plug?

If all the components are rated to 220V, yes. Keep in mind that if the appliance was designed for 110V it may arc if 220 is run through it. If you don't know the device can handle 220V, don't run it at 220V. Chances are it was manufactured cleaply and cannot handle the extra voltage.


Can i use a 220 volt ac in the basement to run branch circuits for 110 volt lighting?

Yes, you can use 220V to 110V step-down transformers for this purpose.


120V gas Kenmore dryer and the hook up location has the big 240V female receptacle--what is easiest solution thanks?

The easiest solution is to leave the 220V original outlet alone and plug the 110V dryer into a close 110V outlet, most likely the one for the washer. There should be nearby 110V outlets so you don't have to muck with rewiring the 220V outlet. A short heavy-duty extension cord is an option. I would also recommend killing the power to the old dryer outlet if it is unused. It cannot hurt. If you cannot plug the dryer into a nearby 110V outlet you can derate the 220V outlet down to a dedicated 110V outlet. This is not a task to be taken lightly if you are not experienced. If you do take this course of action yourself, buy a book. Do it right or don't do it at all. Negligence could kill someone.


Can i get 9V to 110V transformer in the market?

Sure. You can go a couple of ways. You can look for a 110v to 9v transformer, if you can find one, or you can get a 110v to 18v center tapped transformer. If you get the second one, when you hook up the 9v side, you connect between one of the ends of the 18v coil and the center tap. Right now you're thinking, "I said a 9v to 110v transformer, not a 110v to 9v." That you did, but transformers don't care about that--they'll step voltage up as readily as they'll step it down. (Back when all we had was tubes to work with, transformers with a 6v winding and a high-voltage winding--300v, 400v, 2500v, whatever--were very common because tubes need a LOT of voltage to work.) There are two things you really should think about here if you're trying to take 9v to 110v. First, if your intention was to get line voltage out of a 9-volt battery, stop right here. Transformers only work with AC voltage, and a battery puts out DC. The other thing is, if you've got 9v AC and you feed it into a transformer that will give 1A at 9V, 0.08A at 110V will come out of the unit. Eight one-hundredths of an amp isn't really enough to do anything with. If you want to get 1A worth of 110v from 9v, you need to feed (assuming perfect efficiency in the transformer, which you will not get) 12.5A at 9v, or 25A at 9v if you have a transformer with a more likely 50 percent efficiency. It's possible to step 9v up to 110v, but it's probably not worth your time to do so.


How do you rewire a 220v lamp for 120v?

If your trying to plug in a 110 Volt lamp into 240 volt outlet the answer is simple. You must buy a step down transformer, or your lamp will burn out.

What do you need to do to convert a 220V waterfall picture to 110V?

You need to acquire a 110V to 220V step-up transformer. Just be sure to take into consideration the frequency of the AC voltage. I believe the UK runs at 50 hz. and the US is at 60 hz. What that means to you is that the waterfall will run faster here in the States. Also be sure that the transformer's output will match the power consumption of the device you're going to power with it. Do they make such a device? Yes, but you can also use a 220V to 110V step-down transformer in reverse. (Providing it's just a transformer.)


Can you run a 60hz 110V motor on 50 hz 220V with a step down transformer?

NO dear we can not rotate a 110 vlolt motor on 220,but if your voltage is 110v then y can rotate it on 50hz ,no problem,but it will rotate at lower speed, ENGR. NASEER AHMED,PAKISTAN


I have a 1960 vintage Juke Box that runs on European 220v 50Hz power. Is there a device I can purchase that will convert US 110v 60Hz power to run this machine?

Yes, purchase a step-down transformer.


How can you step down 220v ac to 150v ac?

What is known as control transformer?

THIS IS ONLY DESCRIPTIVE NAME - THE TRANSFORMER USED IN CONTROL PANELS ARE USED FOR STEPPING DOWN TO A LOWER AND SAFER VOLTAGE HANDLING BY TECHNICIANS - 220V,110V, 48V, 24V, 12V, 6V. USUALLY FOR THE COILS OF CONTACTORS, RELAYS, TIMERS, PROTECTIVE DEVICES, PILOT LAMPS, METERINGS.


Can you power American equipment from a 220 -125v step-down transformer or must it be 110v?

No


Can a 5.8 ampere 110V run on a step up step down 300 W transformer?

No because the load is 638 VA which is too much for the transformer.

How can you step down a 15kv transformer single phase to 220v?

A transformer steps the voltage of an electrical power supply up or down. The transformer must be correctly designed for the voltage and current levels that it is intended for. Only ac can be used with a transformer, which is designed to work at a particular frequency.

Can 110V appliances be used in 220V countries I have lighting and heating appliances which i bought while i was in the US. Now moved to India. Can i use these appliances directly with a 220V source.?

No, they will burn out. the wiring, motors and modules are built to run on and withstand 110v. There are rectifiers that you can buy to reduce the voltage to your appliances. Get ahold of a local electrician and explain the problem. I'm sure you'll be able to get some help. You can use 110v appliances in countries that use 220v, IF you have an adapter (step down transformer) ... you cannot plug them directly into the 220v source for several reasons: 1. The plugs won't match up as the power plug configurations are much different 2. The appliances will literally blow up of catch on fire if you exceed the voltage limit specified on their labels. If you have moved permanently to India and are staying there, it might be in your best interests to buy new appliances.
