Current in an ac circuit is given by\[i=3\,\sin \,\omega t+4\,\cos \,\omega t\] then

if voltage applied is \[V={{V}_{m}}\,\sin \,\omega t\], the circuit may contain resistance and inductance.

mean value of this current in one half period will be \[6/\pi \]

if voltage applied is \[V={{V}_{m\,}}\sin \,\omega t\] then the circuit must be containing resistance and capacitance.
