Assignment:
In the circuit shown in the figure below the capacitor has capacitance C = 30 μF and is initially charged to 100 V with the polarity shown. The resistor R0 has resistance 10 R. At time t = 0 the switch is closed. The small circuit is not connected in any way to the large one. The wire of the small circuit has a resistance of 1.0 film and contains 28 loops. The large circuit is a rectangle 2.0 m by 4.0 m, while the small one has dimensions a = 10.0 cm and b = 20.0 cm. The distance c is 5.0 cm. (The figure is not drawn to scale.) Both circuits are held stationary. Assume that only the wire nearest the small circuit produces an appreciable magnetic field through it.
