We can use Kirchoff 2 (loop) to write a differential equation for current I If & is the emf of the battery and - is the emf generated in the coil, the sum of these two should equal the potential difference across the resistor, IR. assuming I = 0 Write down and solve the differential equation, when t = 0 HE Ch.8 Physics... Now consider what happens to the bottom loop when we open the switch. There is now only one source of EMF. Write down and solve a differential equation in for this case, assuming that the current at, when the switch was opened, was 1
