A circular coil with N1=5000 turns is made of a conducting material with resistance 0.0100 Ω/m and radius a=40.0cm. The coil is attached to a C=10.00μFC capacitor as shown in (Figure 1). A second coil with radius b=4.00cm, made of the same wire, with N2=100 turns, is concentric with the first coil and parallel to it. The capacitor has a charge of +100 μC on its upper plate, and the switch S is open. At time t=0 the switch is closed.
(d) What is the direction of the current in the smaller coil at t = 1.26 msms?
(e) What is the magnitude of the current in the smaller coil at t = 1.26 ms?
The bolt of lightning depicted in the figure below passes 200 m from a 105-turn coil oriented as shown. If the current in the lightning bolt falls from 6.01 ✕ 106 A to zero in 10.9 μs, what is the average voltage induced in the coil? Assume the distance to the center of the coil determines the average magnetic field at the coil's position. Treat the lightning bolt as a long, vertical wire. µ0 = 4π x 10-7 Tm/A
