Question

What is the applied voltage at any instant when a capacitor is connected to an AC source?

Options

• \[v=v_m\sin\omega t\]

• \[v=v_m\sin 2\omega t\]

• \[v=v_m\cos\omega t\]

• \[v=\omega Cv_m\sin\omega t\]

Answer 1

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