Current in an ac circuit is given by

I=3 \sin \omega t+4

\cos \omega t

then

View answer and explanation

Correct option: C

if voltage applied is

V=V_m \sin \omega t

then the circuit must be containing resistance and capacitance

Option C (if voltage applied is

V=V_m \sin \omega t

then the circuit must be containing resistance and capacitance) is correct because the current has both sine and cosine components, indicating a phase shift that can only be achieved with both resistance and capacitance.
