Close
Step 1
Step 1: For a DC series RL circuit, the maximum (steady-state) current occurs long after the switch is closed when the inductor behaves like a short circuit, so I_max = V/R. Show more…

A series LR circuit contains an emf source of 11 V having no internal resistance, a resistor, a 34 H inductor having no appreciable resistance, and a switch. If the emf across the inductor is 80% of its maximum value 2 s after the switch is closed, what is the resistance of the resistor?
