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.

Explanation / Answer

at t= o the current is zero as inductor behave as a open cct at t=t i=integral v/L+r limits are 0-t
