Question

If the coeeffiecient of mutual induction of peimary and secondary coil is 4h and a current 8 a is cut off in 4ms in prumary coil the emf induced in secondary coil

Answer 1

Answer:

Moreover, the number of coil wraps affect its inductance in that all factors kept constant, if the number of coil turns is greater, then there is high inductance and vice versa. The coefficient of coupling refers to the magnetic flux fraction emanated by a specific coil that has a link with another coil.
