A 1.7 H inductor has a current of 6.6 A flowing through it. The current reduces to 3.3 A over a period of 1.6 s. What is the average power the inductor supplies to the circuit as the current reduces?
A) 17 W
B) 37 W
C) 9.3 W
D) 28 W
E) 46 W

The average power supplied by the inductor is calculated using the formula P = 0.5 * L * (I1^2 - I2^2) / t, where L is inductance, I1 and I2 are initial and final currents, and t is time. Substituting the given values: P = 0.5 * 1.7 * (6.6^2 - 3.3^2) / 1.6 = 17 W.
