Series RL Circuit

An electrical circuit consisting of a resistor (R) and an inductor (L) connected in series, displaying characteristics dependent on the combined effects of resistance and inductive reactance.

Inductive Reactance

The impedance offered by inductors in a circuit to the flow of alternating current, determined by the frequency of the current and the inductance of the inductor.

Series Circuit
