For the circuit shown in Fig. 7, what is the rate of change of the current
in the inductor when the current in the battery is 0.50 A?
(1) 600 A/s (2) 400 A/s (3) 200 A/s (4) 800 A/s (5) 500 A/s
induced emf = L (dI/dt)
The Attempt at a Solution
I didn't fully understand the problem. I don't understand why the current in the battery was given? What would I use that value for?
Please explain to me what I need to know to find out the rate of change of the current. Thank you very much.
