The mutual inductance between two coils is 1.25 henry. If the current in the primary changes at the rate of 80 ampere/second, then the induced e.m.f. in the secondary is

A

12.5 V

B

64.0 V

C

0.016 V

D

100.0 V

Answer

100.0 V

Explanation

Solution

e=Mdidt=1.25×80=100 Ve = M \frac { d i } { d t } = 1.25 \times 80 = 100 \mathrm {~V}
