In the circuit shown in the figure, the inductor has inductance L = 4.00 H and negligible internal resistance. The battery has a voltage of Vb = 11.0 V and is connected in series to a resistor of resistance R1 = 15.0 Ω. A second resistor has a resistance of R2 = 145 Ω. The switch S has been closed for a long time. At time t = 0, the switch is opened. What is the current Ib,0 in the battery, the current I2,0 in resistor R2, and the current IL,0 in the inductor at t = 0. Ib,0 = A I2,0 = A I2,∞ = A Ib,∞ = A IL,∞ = A
