Question

1. The switch of Figure 14-39 is closed at t = 0 s. How long is it until current reaches its steady value?
2. An unknown circuit containing dc sources and resistors has an open-circuit voltage of 45 volts. When its output terminals are shorted, the short-circuit current is 0.15 A. A switch, resistor, and inductance are connected in Figure 14–48. Determine the inductor current and voltage 2.5 ms after the switch is closed.

1. The switch of Figure 14-39 is closed at t = 0 s. How long is it until current reaches its steady value?
Solution: This is simple RL Circuit. 
Time Constant = L/R = 3/60= 1/20 =0.05 sec 
Time Taken to reach steady state = 5* Time constant= 5* 0.05 = 0.25 sec
