| voltage |
The driving force behind the flow of electricity somewhat like pressure is in a water pipe. Most homes are wired with '110' and '220' volt lines. The '110' volt power is used for lighting and most of the other circuits. The '220' volt power is usually used for the kitchen stove, water heater and dryer. (The terms '110' and '220' volts are a short hand, eg a '110' volt line is usually rated at 117 volts plus or minus 10%).

The (electrical) potential difference between two points in a circuit. The fundamental unit is derived as work per unit charge-(V = W/Q). One volt is the potential difference required to move one coulomb of charge between two points in a circuit while using one joule of energy.
