Two coil A and B are placed in a circuit...

Two coil A and B are placed in a circuit. When current changes by 8 Amps in the coil A, the magnetic flux change of 1.6 weber occurs in B. Then the mutual inductance of the coil is:

A

0.2 H

B

12.8 H

C

0.025 H

D

5.0 H

Text Solution

Verified by Experts

The correct Answer is:
A
`phi_(s) = MdI_(P) :. M = (phi_s)/(dI_(P)) = 1.6/8 = 0.2 H`.
