Why is 220V better than 110V?
A 110-VOLT supply is less likely to electrocute you. A 220-volt supply can transmit the power more cheaply because a smaller current is needed, and so you can use thinner cables and/or lose less energy through heat generated in the cables.
Is 220V more efficient than 120V?
Originally Answered: Electrical Engineering: Which is more efficient to use 220v or 110v? For a given wire diameter, 220 or 240V will be have lower losses than 110 or 120V, because the higher voltage circuit will use half the current.
Is it cheaper to run a 110 or 220 air conditioner?
A 110 volt a/c usually uses less power than a 220 volt simply because it has less cooling capacity. They roughly use the same kwh per btu, meaning they cost the same in electricity to do the same amount of cooling.
