Q. The current $'i'$ in an inductance coil varies with time ‘$t$’ according to following graph Which of the following plots shows the variation of voltage in the coil
A)
B)
C)
D)
Explanation
(b) (1) For time interval $0 < t < T/2$
$I = kt$, where $k$ is the slope
For inductor as we know, induced voltage $V = - L\frac{di}{dt}$
$\Rightarrow V_{1} = - KL$
(2) For time interval $\frac{T}{2} < t < T$
$I = - Kt \Rightarrow V_{2} = KL$
