Title: A coil with a self-inductance of 6.0 H is connected to a dc source through.. Post by: bdukie on Nov 18, 2013 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 Title: Re: A coil with a self-inductance of 6.0 H is connected to a dc source through.. Post by: padre on Nov 18, 2013 giventhat
L = 6 H change of current di/dt = 2A/s induced emf ε = L di/dt = 12 v |
