A solenoid has a cross-sectional area of 7.7 x 104 m², consists of 380 turns per meter, and carries a current of 0.54 A. A 20-turn coil is wrapped tightly around the circumference of the solenoid. The ends of the coil are connected to a 1.7-a resistor. Suddenly, a switch is opened, and the current in the solenoid dies to zero in a time of 0.051 s. Find the average current induced in the coil.
