Problem 3.335

A coil of inductance \(L=2.0 \mu \mathrm{H}\) and resistance \(R=1.0 \Omega\) is connected to a source of constant emf \(\mathscr{E}=3.0 \mathrm{~V}\) (Fig. 3.96). A resistance \(R_{0}=2.0 \Omega\) is connected in parallel with the coil. Find the amount of heat generated in the coil after the switch \(S w\) is disconnected. The internal resistance of the source is negligible.
