What is the self-inductance in a coil that experiences a 3.0-V induced emf when the current is changing at a rate of 37 A/s?
A) 81 mH
B) 37 mH
C) 27 mH
D) 45 mH

The self-inductance of a coil is given by the equation L = emf / (di/dt), where emf is the induced electromotive force, di/dt is the rate of change of current, and L is the self-inductance. In this case, the emf is 3.0 V and the rate of change of current is 37 A/s, so the self-inductance is L = 3.0 V / 37 A/s = 81 mH.
