# Current (Electrical)

Written by Jerry Ratzlaff. Posted in Electrical

Current 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

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

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

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