A security alarm for an office building door is modeled by the circuit
shown. The switch represents the door interlock, and V is the alarm
indicator voltage. Find the current through the inductor, iL(t), for
t>0. The switch has been closed for a long time at t=0.
A) 2 A
B) 2e(-t/24) A
C) 2e(-24t) A
D) 4e(-24t)
