An emf of 123.0 mV is induced in the windings of a coil when the current in a nearby coil is increasing at the rate of 1.17 A/s. What is the mutual inductance of the two coils?
A 0.91-µF capacitor is charged by a 39.0-V power supply. The fully charged capacitor is then discharged through a 9.9-mH inductor. Find the maximum current in the resulting oscillations.
