A coil of inductance L = 2.0 mu H and...

A coil of inductance `L = 2.0 mu H` and resitance `R = 1.0 Omega` is connected to a source of constant `emf E = 3.0 V`. A resistance `R_(s) = 2.0 Omega` is connected in parallel with the coil. Find the amount of heat generated in the coil after the swich `Sw` is disconnecied. The internal resistance of the source is negligible.
