Two coils, held in fixed positions, have a mutual inductance of 100 µH. What is the peak emf in
one coil when the current in the other coil is i(t) = 10.0 sin (1.00 x 10³t), where i is in amperes
and t is in seconds?
At time t = 0, a 12.0 V potential difference is suddenly applied to the leads of a coil of inductance 23.0 mH and a certain resistance R. At time t = 0.150 ms, the current through the inductor is changing at the rate of 280 A/s. Evaluate R.
At time t =0, a 45 V potential difference is suddenly applied to the leads of a coil with inductance L= 50 mH and resistance R = 180 ohm. At what rate is the current through the coil increasing at t = 1.2 ms?
