An electromotive force that moves the electrons in an electrical flow. It is measured in Volts (V).

The charge capacity of a battery. It is measured in Ampere hours (AH).

An electrical resistance divided by an electrical voltage. It is measured in Watts (W).

The flow of electric charge per time unit. It is measured in Amperes (A).
