A coil with a self-inductance of 6.0 H is connected to a dc source through a switch. As soon as the switch is closed at t = 0 s, the rate of change of current is 2.0 A/s. What is the emf induced in this coil at t = 0 s?
A. 12 V
B. 6.0 V
C. 3.0 V
D. 0 V
E. 1/3 V

giventhat
L = 6 H
change of current di/dt = 2A/s
induced emf ε = L di/dt
= 12 v
