A coil of inductance
L=2.0 μH and resistance
R=1.0 Ω is connected to a source of constant emf
ϵ=3.0 V
resistance
R0=2.0 Ω is connected in parallel with the coil.The amount of heat generated in the coil after the switch
Sw is disconected (in microjoule) is
(The internal resistance of the source is negligible.)
