Question

Which expression describes alternating voltage that varies sinusoidally with time?

पर्याय

• \[\overline{P}=\frac{1}{2}v_mi_m\]

• \[v=v_m\sin\omega t\]

• \[i=i_m\sin\omega t\]

• \[v=iR\]

Answer 1

Alternating voltage varies sinusoidally with time as \[v=v_m\sin\omega t\]. Here, \[v_m\] is its peak voltage.
