Q1: A voltage v = 5 + 50 sin ωt/ + 5 sin 5 &omegat is applied to a pure capacitor of capacitance 1 ωF. If f/= 314 rad/sec, current is

A 1 + 0.0157 cos 314 t+ 0.00785 cos 1570 t

B 0.0157 cos 314 t + 0.00785 cos 1570 t

C 0.0157 sin 314 t + 0.00785 sin 1570 t

D 0.0157 sin (314 t / + 45°) + 0.00785 sin (1570 t + 45°)

ANS:B - 0.0157 cos 314 t + 0.00785 cos 1570 t
