The time constant of rl circuit is l/r

WebTransient Response of RL Circuit The Natural Response of an RL Circuit The natural response of an RL circuit can best be described in terms of the circuit shown in Fig. 1.We assume that the independent current source generates a constant current of Is A, and that the switch has been in a closed position for a long time. These equations show that a series RL circuit has a time constant, usually denoted τ = L / R being the time it takes the voltage across the component to either fall (across the inductor) or rise (across the resistor) to within 1 / e of its final value. That is, τ is the time it takes V L to reach V(1 / e) and V R to reach V(1 − 1 / e).
