Current changing from 8 A to 12 A in one second induced 20 volts in a coil. The value of inductance is___________?
Correct answer: C. 5 H
- A. 5 mH
- B. 10 mH
- C. 5 H
- D. 10 H
Explanation
Using V = L(di/dt), the current changes by 12 − 8 = 4 A in 1 second, so L = 20/4 = 5 H. Therefore, option c is correct.
