The equation of current in a purely inductive circuit is 5 \sin (49 \pi t-30^{\circ}). If the inductance is 30 {\mH} then the equation for the voltage across the inductor, will be : \{. Let .\pi=\frac{22}{7}\} [28-Jul-2022-Shift-1]

Correct Answer is : 23.1sin(49πt+60∘)

1.47 \sin (49 \pi t-30^{\circ})

1.47 \sin (49 \pi t+60^{\circ})

23.1 \sin (49 \pi t-30^{\circ})

23.1 \sin (49 \pi t+60^{\circ})
