Current over Time in a Series RL Circuit#

Consider the \(RL\) circuit shown below.


Question Text#

How long after switch \(\rm S\) is thrown does it take the current in the circuit to reach \(1/{{ params_fac }}\) of its maximum value? Express your answer in terms of the time constant \(\tau_L\) of the circuit.

Answer Section#



\(t =\) \(\tau_L\).
