# what is the difference between 110V and 220V? which is cheaper between the two?

Your electric bill is based on kilowatt hours. A kilowatt hour (KWh) cost the same regardless of voltage so there is no difference in cost between 110 VAC or 220 VAC.

The reason for the two voltages is that some appliances, such as your stove, dryer, water heater, draw a lot of power. A water heater is typically 4400 watts. At 110 volts this would be 40 amps. That would take a big wire. At 220 volts, 4400 watts only takes 20 amps. You don't need as big a wire for the same power. The lower current is also a little safer as the potential heating in the wiring is reduced.

This is also why most 110 VAC appliances are limited to about 1200 to 1500 watts. 1200 watts on a 110 VAC circuit is just under 11 amps. 1500 watts is just over 13.5 amps. Most houses have 20 amp circuit breakers but older houses may have 15 amp breakers or fuses. You want some headroom in your fuse or circuit breaker so you don't want to draw 15 amps from a 15 amp fuse or circuit breaker or 20 amps from a 20 amp breaker.

110 is used un the US and in Japan. 220V is an European standard. Probably both used in other countries around the world I don't know all of them.

In most of the countries there is one state standard voltage what you can get. Eg probably in the US you can get 110V only from a standard wall connector. Also In europe in the UK for example there is almost no way to get 110V as standard anywhere so the question as which is cheaper is pointless really.

The difference between them is the voltage. All electric circuits you want to use must be able tu handle the standard you are using: e.g. a tv designed to handle 110V will blow up (well some purts inside :) )if you plug it into 240V etc.

The difference is very large. 110V is normal electricity you get from your average wall plug. 220V is two-phase electricity normally for your Stove or Dryer or other high voltage equipment.

If you are asking because there is a switch on a piece of equipment for this, then it's because it switches between 50 hz and 60 hz electricity. Using the WRONG setting can and WILL kill your electronics.

In North America we use 60Hz, in Europe they use 50Hz.

To answer your question, neither is any cheaper 'typically' but which of the two situations I described are you talking about?

1. 110V took more Current according to load than 220V

2. Wire thick than 220V due to current increase

4. Due to high current Electric appliances may demaged

5. Cooling agents will indused than 220V appliances

110 Volts, both are AC (Alternating Currents) There is no difference except for the amount. The opposite to AC is however DC. 110V is most common in the USA, while the Canadians use 120V. In Europe the voltage is commonly 220V - 240V. It only means you can draw greater "voltage" for your electric machines and appliances. It also means one must be careful not to cross or plug a lower voltage appliance into higher voltage outputs or visa versa.

For the same power rating 120 V appliances draw more current as compared to 220 V. But comparing both 110v with 220v wiring, you have to keep in mind that they both essentially do the same thing. That is, they produce power to operate electrical outlets. The equation is as follows: Power = Voltage x Current with current measured in amps. When 220v wiring is used, less current is required than with 110v wiring. Power is measured in watts. Thus, to achieve 900 watts of power, 4.1 amps would be required with 220v wiring, whereas approximately 8.2 amps would be required with 110v wiring.
