What will be an ideal response?
LR Circuits: The figure shows a circuit. The ideal battery has a constant terminal voltage of ? = 27 V, the inductance is L = 0.40 H, and the resistances are R1 = 12 ? and R2 = 9.0 ?. Initially the switch S is open with no currents flowing. Then the switch is suddenly closed.(a) What is the current in the resistor R1 the instant after the switch is closed?(b) After leaving the switch has been closed for a very long time, it is opened again. Just after it is opened, what is the current in R1?
