Consider the \(RL\) circuit shown below.

../../../../../_images/fig_OSUPv2p14_57.png

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 \(\rm\ \Omega\).
