A small signal voltage `V(t)=V_(0)sin omegat` is applied across an ideal capacitor `C`:

A small signal voltage V(t) = V_0sinomegat is applied across an ideal capacitor C.

Explain the term 'capacitive reactance'.Show graphically the variation of capacitive reactance with frequency of the applied alternating voltage. An a.c. voltage E=E_(0) sin omegat is applied a across a pure capacitor C .Show mathematically that the current flowing through it leads the applied voltage by a phase angle of pi//2

An alternating voltage V = V_(0) sin omegat is applied across a circuit. As a result, a current I = I_(0) sin (omegat – p/2) flows in it. The power consumed per cycle is
