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?
A. 0.6 A
B. 0.3 A
C. 0.2 A
D. 0.1 A
