# Current

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.

## Current (Amp) formulas

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

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

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

### Where:

\(\large{ I }\) = current

\(\large{ P }\) = power

\(\large{ R }\) = resistance

\(\large{ V }\) = volt
