The e.m.f. induced in a secondary coil is `20000 V` when the current breaks in the primary coil. The mutual inductance is `5H` and the current reaches to zero in `10^(-4) sec` in the primary. The maximu current in the primary before it breaks is

An emf induced in a secondary coil is 10000 V when the current breaks in the primary. The mutual inductance is 5 H and the current reaches to zero in 10^(-4) s in primary. The maximum current in the primary before the breaks is

The average emf induced in the secondary coil is 0.1 V when the current in the primary coil changes from 1 to 2A in 0.1 s .What is the mutual inductance of the coils.

The average emf induced in the secondary coil is 0.1 V when the current in the primary coil changes from 1 to 2A in 0.1 s .What is the mutual inductance of the coils.

How is induced current in a secondary coil related to current in a primary coil ?

A certain current flows in the primary of an induction coil of mutual inductance 5 H. when the break occurs, an emf of 30,000 V is induced in the secondary. If the current in the primary falls uniformly to zero in 10^(-4) s, find the current in the primary just before the break?
