Question

Two coils, A and B, are lined such that emf ε is induced in B when the current in A is changing at the rate I. If current i is now made to flow in B, the flux linked with A will be ______.

Options

• (ε/I)i 

• εi I

• (ε I)i 

• i I/ε

Answer 1

Two coils, A and B, are lined such that emf ε is induced in B when the current in A is changing at the rate I. If current i is now made to flow in B, the flux linked with A will be (ε/I)i.
