Magnetic flux linked with a coil is $\phi = 5t^{2} + 2t + 3,$ where t is second and $\phi$ is in weber. At time t =1 s, the value of induced emf in volt

Question

Dr. Abubacker · Accepted Answer

(c) Given, magnetic flux, $\phi = 5t^{2} + 2t + 3$
The value of induced emf $\frac{d\phi}{dt} = 10t + 2$
At $t$=1
The value of induced emf $\frac{d\phi}{dt} = 12\ V$
