Current, I, is a movement of charge over time and is expressed in amperes, A, where 1 ampere is equivalent to 1 coulomb/sec. In this section we review the convention used to describe currents ...Current, I, is a movement of charge over time and is expressed in amperes, A, where 1 ampere is equivalent to 1 coulomb/sec. In this section we review the convention used to describe currents in electrical circuits and review four laws of electricity.
