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