Electric charge

Quantity of electricity

Definition

The electric charge or quantity of electricity is the physical measure, which defines the intensity of the current flowing through the conductor cross-section in a period of time. This is a scalar measure that identifies the state of electrification of the bodies.

1 coulomb is the electric charge or quantity of electricity which passes through the cross section at a current of 1 ampere in 1 second.
