Question
Consider an L-R circuit as shown in the figure. (Figure 1) The battery provides 12.0 V of voltage. The inductor has inductance L, and the resistor has resistance R= 150 omega . The switch is initially open as shown. At time t=0, the switch is closed. At time t after t=0 the current I(t) flows through the circuit as indicated in the figure.The current in the circuit will approach a constant value Ic after a long time (as t tends to infinity). What is Ic? Ic=_____Amperes
same figure as here

Explanation / Answer
V = I*R so I = V/R
I = 12 / 150 = 0.08 A
