Question
The equation of current in a purely inductive circuit is $5 \sin \left(49 \pi t-30^{\circ}\right)$. If the inductance is 30 mH then the equation for the voltage across the inductor, will be : $\left\{\right.$ Let $\left.\pi=\frac{22}{7}\right\}$
Select the correct option:
A
$1.47 \sin \left(49 \pi t-30^{\circ}\right)$
B
$1.47 \sin \left(49 \pi t+60^{\circ}\right)$
C
$23.1 \sin \left(49 \pi t-30^{\circ}\right)$
D
$23.1 \sin \left(49 \pi t+60^{\circ}\right)$
