APFIVE Energy Dissipation in an LR Circuit
An LR circuit with inductance L = 0.5 H and resistance R = 10 Ω has a current of 2.0 A. If the source of emf is suddenly removed and the circuit remains closed, how much energy is dissipated as heat during the complete discharge of the inductor?
A
0.5 J
B
2.0 J
C
1.0 J
D
5.0 J
