Question

In a series RL circuit, the resistance is 135 ohms, the inductance is 120 x 10-3 H, and the source of electromotive force is ξ. After some time, the current in the circuit reaches its maximum value, and at this time the energy stored in the inductor is 230 x 10-3 J.

a) What is the value of ξ?

b) Next, we remove the electromotive force source and connect the inductor directly to the resistor. How long will it take for the energy stored in the inductor to decrease to half of its initial value?
