Alternating Current

Potential difference across resistance \(\mathrm{R}\) and that across capacitor have phase difference \(\frac{\pi^{\mathrm{c}}}{2}\).

Applied e.m.f. and potential difference across resistance '\(R\)' are in the same phase

Applied e.m.f. and potential difference inductor coil has phase difference of \(\frac{\pi^{\mathrm{c}}}{2}\)

Potential difference across capacitor and that across inductor have phase difference of \(\frac{\pi^{\mathrm{c}}}{2}\).
