As we learnt in

Equation of V -

V= V_{0}\sin \omega t=V_{0}\sin 2\: \pi\: \nu\: t

V= V_{0}\sin \frac{2\pi }{T}t

- wherein

\omega= Angular frequency

\nu = Frequency

T =  time period

 

 

V(t) = V_{o} sinwt (t_{o} \gg \frac{L}{R})

I = I_{o} cos (wt + \phi )


Option 1)

This option is incorrect.

Option 2)

This option is correct.

Option 3)

This option is incorrect.

Option 4)

This option is incorrect.
