Ohms Law

Ohms Law. Ohms Law is used to describe The relationship of voltage (E or V), resistance (R) and current (I) in an electric circuit. Simply stated voltage in a circuit is equal to resistance [in ohms] times the current [in amps]. It applies to both loads and sources in all circuits. Mathematically, Ohms Law is described as: V = I x R where V = volts I = Amps and R = ohms.
