difference between 110v and 220v?

Answer 1

Voltage is analogous to the PRESSURE forcing water through a pipe, and electric current is analogous to the liquid FLOWRATE. 220 volts is twice the "electrical pressure" of 110 volts, so it would force twice as much electrical current (amperes) through an appliance as 110 volts would.

As other answerers have noted, the appliance plugs are usually designed so that you cannot do this by accident.

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

In USA 110V is supplied by the Company and for appliances . But in Some parts of world and Most of Asia and Africa 220V is the voltage supplied. The appliances used in these regions has that much resistivity.
Now, From the below expressions we can just see. In 220V more current is required and it is a costly process than 110V
V = I x R
Where, V is Voltage; I is Current and R is Resistance.

Answer 4

110 V (sometimes also referred to as 115V or 120V) is the voltage of a typical electrical receptacle in your house. It has 1 hot wire ("leg"), and one neutral wire, and usually a ground wire as well. 220V service is required for higher power consuming products, and consists of an additional (2nd) hot wire, plus the neutral and ground. Appliances such as an electric clothes dryers, central air conditioner units, and ovens/stove often require 220V service, and the receptacle is configured differently to help avoid confusion.

It think some people may be confusing the frequency (Hertz, or cycles per second) when referring to other countries..in the US, it's generated at 60 Hertz, whereas it's 50 Hertz is some European countries.

Answer 5

110v means inspiring source of movement for classical dance & 220v means inspiring source of movement for Break Dance. More simplifying it is that, the level amount of electrical energy flow & speed.

Answer 6

Generally the difference can be both amperage and number of phases (and of course the voltage, duh) with the 220 often but not always having more of both. The typical U.S. house is wired with (mostly) single phase, 110 v, 10 - 20 amp fused circuits. Larger household appliances are often 220v two phase.

Answer 7

110 volt power is a 3 wire power supply, one wire is black having 110 volts, one white witch is neutrial, one ground wire that is bare. 220 volt power supply is 4 wire , two of the wires have 110 volt each , one neutrial and one ground.

Answer 8

Refer to earlier question "Advantages of 110 volts over 220volts"

Answer 9

These days it's closer to 125 and 250 volts.

Answer 10

It is 110 volts .
