In the circuit shown below, a 100 V battery is connected to R1 = 10.0 Ω, R2 = 20.0 Ω, R3 = 30.0 Ω, and L1 = 2.00 H. The switch is closed at t = 0 s.

(a) What is the current through each resistor in the circuit at the instant the switch is closed?
(b) As t = 3, what is the current through each resistor?
(c) As t = 3, how much energy is stored in the magnetic field of the inductor?
