The mutual inductance of a pair of coils, each of ' N ' turns, is ' M ' henry. If a current of ' I ' ampere in one of the coils is brought to zero in ' t ' second, the e. m. f. induced per turn in the other coil in volt is
Options
- AMI t
- BNMI t
- CNM It
- DMI Nt
Correct answer
A. MI t
Step-by-step solution
Emf induced due to mutual inductance per coil, e = M I t Here, the current changes from I to zero in time t seconds. e = MI t
