In the circuit shown in the figure, the inductor has inductance L = 3.75 H and negligible internal resistance. The battery has a voltage of Vb = 18.0 V and is connected in series to a resistor of resistance R1 = 12.0 Ģ. A second resistor has a resistance of R2 = 145 Ģ. The switch S has been open for a long time. At time t = 0, the switch is closed.
What is the current Ib,0 through the battery, the current I2,0 through resistor R2, and the current IL,0 through the inductor at t = 0?
What is the current Ib,ā through the battery, the current I2,ā through resistor R2, and the current IL,ā through the inductor long after the switch is closed (i.e., t = ā).
