1) If an inductor of inductance 0.100 mH is used to store the same amount of energy of a charged capacitor that has a capacitance of 4.00 microF and 40.0 microC on its positive plate, what is the current going through the inductor?
2) Determine the maximum countertorque (magnitude) created in the coil of a generator that delivers 121 W of average power to a resistor at a frequency of 50.0 Hz.
3) A small round coil of radius 1.00 mm and 20 turns is at the center of a larger round coil of radius of 10.0 cm and 100 turns. Both coils have the same orientation. Find the mutual inductance between these two coils.
