Question:
In Section 9.2 we modeled the current I(t) in the electric circuit shown in Figure 5 by the differential equation
Find an expression for the current in a circuit where the resistance is 12Ω, the inductance is 4 H, a battery gives a constant voltage of 60 V, and the switch is turned on when t = 0. What is the limiting value of the current?
