A pair of adjacent coils has a mutual inductance of 2.0 H . If the current in one coil changes from 0 to 30 A in 0.5 s, the change of the magnetic flux linked with the other coil would be
- A 30 Wb
- B 120 Wb
- C 50 Wb
- D 60 Wb
Answer & Solution
Correct Answer
(D) 60 Wb
Step-by-step Solution
Detailed explanation
\( \Delta \Phi = M \Delta I \) \( \Delta \Phi = (2.0 \, \text{H})(30 \, \text{A}) \) \( \Delta \Phi = 60 \, \text{Wb} \)
