The megnetic flux lines of 3 xx 10^(-4) ...

The megnetic flux lines of `3 xx 10^(-4)` Wb are passing through a coil of 100 turns. If the e.m.f. Induced in the coil is 1.5V, the time interval will be

A

1 sec

B

0.1 sec

C

0.02 sec

D

0.4 sec

Text Solution

Verified by Experts

The correct Answer is:
C
`e = (Ndphi)/(dt) :. dt = (Ndphi)/(e) = (100xx3xx10^(-4))/(1.5)`
` = 2 xx 10^(-2)s=0.02 s`.
