(1) Volt-One volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.

(2)Ampere-
One ampere of current represents one coulomb of electrical charge (6.24 x 1018charge carriers) moving past a specific point in one second.

(3)Ohm-
The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.

(4)potential-
the quantity determining the energy of mass in a gravitational field or of charge in an electric field.

(5)resistivity-
a measure of the resisting power of a specified material to the flow of an electric current.

(6)Electric power-
Electric power is the rate at which electrical energy is transferred by an electric circuit.
