Current

Written by Jerry Ratzlaff on . Posted in Electromagnetism

Current (I) is the rate of flow of electricity in a circuit, measured in amperes.

Amp is a unit of current. One ampere (amp) is the current flowing through one ohm of resistance at one volt potential.

FORMULA

\(Amps = \frac{Volts}{Ohms}\;\; = \;\;I = \frac{V}{R}\)

\(Amps = \frac{Watts}{Volts}\;\; = \;\;I = \frac{P}{V}\)

\(Amps = \sqrt{\frac{Watts}{Ohms}}\;\; = \;\;I = \sqrt{\frac{P}{R}}\)
