##### Reference no: EM13667922

Two coils of wire are located close together. Initially, a current of 3.73 Amp exists in one of the coils, but there is no current in the other. The current is then switched off in a time of 2.67 x 10-2 second. During this time, the average emf induced in the other coil is 3.04 Volt.
