If AC voltage is applied to a pure capacitor, then voltage acrose the capacitor.

In a series LCR circuit at resonance, the phase difference between the current and emf of the source is

For $e=e_{0}sin\omega te\; =\; e\_0\; sin\; \backslash \; \backslash omega\; t$, (average) over one cycle is

For $i=i_{0}sin\omega t\mathrm{.}{i}_{rms}\mathrm{/}{i}_{avg}i\; =\; i\_0\; \backslash \; sin\; \backslash \; \backslash omega\; t.\; i\_\{rms\}\; /i\_\{avg\}$ is

If e = 10 sin(400t) [in volt]. $e_{rms}e\_\{rms\}$ =

In a purely inductive AC circuit, current =
