A pair of adjacent coils has a mutual inductance of 2.0 H. If the current in one coil changes from 0 to 25 A in 0.8 s, the change of flux linkage with the other coil is
- A 50 Wb
- B 62.5 Wb
- C 20 Wb
- D 40 Wb
Answer & Solution
Correct Answer
(A) 50 Wb
Step-by-step Solution
Detailed explanation
\(\Delta \Phi = M \Delta I\) \(\Delta \Phi = (2.0 \text{ H})(25 \text{ A})\) \(\Delta \Phi = 50 \text{ Wb}\)
