Circuit Configuration[edit]

RL Series Open-Closed.svg

Formula[edit]

The total Impedance of the circuit

The 1st order Differential equation of the circuit in equilirium

The root of the equation is a Exponential Decay function chracterised the Natural Response of the circuit


Phase Shift , Change in Frequency relate to change in RL value

Summary[edit]

Series RL is characterised by

1st ordered Differential equation of the circuit at equilibrium.

Natural Reponse of the circuit is the Exponential Decay
