1.

Two coil A and B have coefficient of mutual inductance M=2H. The magnetic flux passing through coil A charges by 4 Weber in 10 seconds due to the change in current in B. ThenA. change in current in B in this time interval is 0.5AB. the change in current in B in this time interval is 2AC. the change in current in B in this time interval is 8AD. a change in current of 1A in coil A will produces change in the flux passing through B by 4Wb
