The current in a coil changes according to the formula: I = 0.5 − 0.2 t where t is in seconds and I is in amps. Experimental measurements show that an emf 0.5mV self-induced voltage is produced at the ends of the coil. What is self-inductance from the coil?
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?
A conducting coil, with current i(t) = 5.40e-0.0250+ sin(120mt), withi in amperes and t in seconds, is placed next to a
second coil, end to end. At t = 0.720 s, a lab tech measures the emf across the second coil, and the result is -3.50 V. What
