The push that moves the electrical current through a conductor.

The unit of potential difference, symbol V. Electricity and magnetism

Electrical system voltage.

The unit of electrical voltage, symbol V

Voltage is the rating of the amount of electrical pressure that causes electricity to flow in the power line. If electricity were water, voltage would measure the amount of pressure at the faucet.

is a basic unit of electric current measurement expressing the potential or pressure of the current. Volts = watts @ amps.

The "pressure" of electrical flow. Can be compared to the pounds per square inch (psi) of water flowing through a pipe. See also: Cut-In, I-V curve, Maximum power, Transformer, Watts

electrical force or pressure behind the electrons in a circuit.

A unit of measure of the pressure in an electrical circuit. Volts are a measure of electric potential. Voltage is often explained using a liquid analogy -- comparing water pressure to voltage: a high pressure hose would be considered high voltage, while a slow-moving stream could be compared to low voltage.

The measurement of electromotive force (EMF). One volt applied to a conductor with resistance of one OHM, will produce one amp of current, the symbol for volts is E, and is used in mathematical equations.

Unit of measurement that represents the power or force of electricity available.

The unit of electromotive force that will force a current of one amp through a resistor or one ohm.

The unit of electrical force or pressure that creates current. Named after Alessandro Volta, an Italian scientist who invented the electric battery in 1800.

measure the force of electricity. The voltage is raised so the electricity can travel a long way through transmission lines. At a substation the voltage is lowered to a safe level before it is brought to our homes and other buildings.
