COMEDK · Physics · 22. Electromagnetic Induction
If a change in current of \(0.01 \mathrm{~A}\) in one coil produces a change in magnetic flux of \(2 \times 10^{-2}\) weber in another coil, then the mutual inductance between coils is
- A 0
- B \(0.5 \mathrm{H}\)
- C \(2 \mathrm{H}\)
- D \(3 \mathrm{H}\)
Answer & Solution
Correct Answer
(C) \(2 \mathrm{H}\)
Step-by-step Solution
Detailed explanation
Given, \(\Delta I=0.01 \mathrm{~A}\) \[ \Delta \phi=2 \times 10^{-2} \mathrm{~Wb} \] We know that, \(\Delta \phi=M \Delta I\) where, \(M\) is mutual inductance between the coils.…
