The current I in an inductance coil varies with time according to the graph shown. Which one of the following plots shows the variation of voltage in the coil with time?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3)
for time interval $0<t_0<t/2$
$I=-Kt$, where $-k$ is slope.
and, for inductor -
$V=-L\frac{di}{dt}⇒v_1=+KL$
$⇒I_1=+Kt$, where K is slope.
