1. Use the exact exponential treatment to find how much time, in milliseconds, is required to bring the current through an 94.3 mH inductor in series with a 15.8 Ω resistor to 82% of its final value, starting from zero.

2. What is the peak emf generated by rotating a 923-turn, 21.1 cm diameter coil in the Earth’s 4.8×10−5 T magnetic field, given the plane of the coil is originally perpendicular to the Earth’s field and is rotated to be parallel to the field in 12.2 ms?
