Question

The mutual inductance between a pair of coils is 3 H. If the current in one coil changes from 0 A to 2 A in 0.5 s, the induced emf produced in the other coil is

• A. 5 V
• B. 2 V
• C. 6 V
• D. 12 V
• E. 3 V

Hint:

Induced emf depends on the rate of change, not just the magnitude of change. Changing current faster (smaller \(\Delta t\)) always leads to higher induced voltages.

Answer 1

The Correct Option is D
