The moment the switch is closed, current flows through the circuit. The resistor has a resistance of R-240 Ω and the inductor has an inductance of L- 55 mH Randomized Variables 9.0V R-240 Ω L=55mH ©theexpert ta.com 20% Part (a) At time 1-0 the switch is closed and current flows through the circuit. The current increases with time and eventually reaches a steady state value of imar.
