When the 28.3 A current through an inductor is turned off in 4.44 ms, an 714 V emf is induced, opposing the change. What is the value of the self-inductance, in mH? Do not enter units with answer.

Step 1
Step 1: The induced emf is given by the equation: $$emf = -L \frac{dI}{dt}$$ where: * emf is the induced electromotive force (in volts) * L is the inductance (in henries) * dI/dt is the rate of change of current (in amperes per second) Show more…
