Question

If coefficient of mutual induction of primary
and secondary coil of transformer is 5 H
and current in primary coil is given as
= 10 sin4000 at. Then peak value of emf
induced in secondary coil is
(1) 5 x 104 volt
(2) T * 105 volt
(3) 271 x 105 volt
(4) 5 x 106 volt​

Answer 1

Answer:

Induced emf in the secondary εs=−MdtdiP=−51/40003=−6×104V

The negative sign merely indicates that the emf opposes the change.
