An ac voltage is applied to a series of LCR circuit. Determine the instantaneous current i and its phase relationship to the applied alternating voltage `nu`.

Explain the physical proces on the basis of which the r.m.s value of AC is defined? Derive the expression for r.m.s value of an alternating voltage. How does the value of Capacitative voltage. How does the value of Capacitative reactance of a capacitor change with the frequecny of the applied alternating e.m.f across it.

Show that an alternating voltage V=V_m sin omegat applied to a resistor R drives a current i= i sin omega t in the resistor.
