Switched RL Series Circuit: Time Constant#
Consider the \(RL\) circuit shown below.

The current in the circuit reaches half of its maximum value in \({{ params_t }}\rm\ ms\) after switch \(\rm S\) is thrown.
Part 1#
Determine the time constant \(\tau_L\) of the circuit.
Answer Section#
Please enter in a numeric value in \(\rm\ s\).
Part 2#
Given \(L = {{ params_L }}\rm\ mH\), determine the resistance \(R\) of the circuit.
Answer Section#
Please enter in a numeric value in \(\rm\ \Omega\).
