Which of the following relations correctly connects the phase difference

\phi

(in rad) between voltage and current with the corresponding time lag

\Delta t

(in s) for an AC source of angular frequency

\omega

? (a)

\phi = \dfrac{\omega\,\Delta t}{2\pi}

(b)

\phi = \omega\,\Delta t

(c)

\omega = \dfrac{2\pi\,\phi}{\Delta t}

(d)

\phi = 2\pi\,\omega\,\Delta t
