Question

The self-inductance and the internal resistance of an inductor are L and R, respectively. A physicist connects the inductor across a battery of voltage V. Under these conditions, the final, steady current in the inductor is I. The physicist then suddenly shortcircuits the inductor with a think (resistanceless) wire placed acriss its terminals. The current then decreases from I initial to I final in a time t.

What is the characteristic time of the circuit consisting of the shorted inductor? Give your answer in terms of the given variables.

torque =
