difference between 110v and 220v?

Answer 1

on a 110 volt system there is one positive wire a neutral wire and a ground. with a 220 volt there is 2 positive wires ( hot wires) and a ground 220 volt is double volts compared to a 110 system. after 220 next is called 440 and then it is called three phase. 110 volts is what most household plugs and 220 is what larger appliances such as a dryer welder or hot water heater operates on.

Answer 2

110 volts. More seriously - 110v is common in the US, 220 in many other areas. A 220v appliance won't run decently, if at all, on 110, and a 110v appliance will burn out if you attempt to run it on 220. The plugs are different, so you can't usually do it accidentally. Voltage refers to how many volts are sent through the electrical power lines.

Answer 3

The basics of electricity generation: there is two types, AC and DC. However as DC can't be transformed (ie, changed up and down), AC is used because the voltage can be stepped up using a transformer to high voltages which therefore reduces the loss to resistence. But, as high voltage is a safety issue when the high voltage lines become closer to the citys and towns they are stepped down to various levels. These levels such as 110v and 220v are both single phase as they are used only for houses. However industries need three phase such as the use of three phase motors, so they use high voltages.

The only difference is the last transformer changes them to a different voltage. It is also wise noting as AC is continuing chaning in the form of a sin wave, we use to equivalent of the DC voltage which is 220v or 100v. Also, as most appliances use low DC voltages such as computers, cordless phones, etc the 110 or 220v is changed again.

In the plug, there is a blue wire (negative), brown wire (positive) and green/and or yellow (earth). As mentioned above ( but sorta wrong), they use to be black (neg) and red (pos) but this was change for colour blind people.

Also, to identify the voltage so you don't plug a 110v appliance and 220v circuit, a different plug is used. If this wasn't the case the extra power would burn out the appliance.

Answer 4

Well the simple answer is voltage, You will have two hot wires usually red and black and one neutral wire sometimes even a ground. A little more in depth on the answer is because you have a higher voltage to carry the wattage you will use less current. As voltage goes up current goes down and your appliance uses less power and becomes cheaper to run. Say for example Welders air compressors and motors become more efficient at the higher voltage.

Answer 5

Twice the voltage. The 220 plug is a different looking one that you usually see on your washer or dryer. 220 isn't very common, so an electrician usually has to install the outlet.

Answer 6

220 - 110 = 110

also typically, "live voltage" in the USA is 110v

and in Europe is 220v ....

tho this is NOT a "hard and fast rule"

Answer 7

220 is twice as much as 110

Answer 8

Different plugs, among other things.

Answer 9

110 volts indeed!
