![Objective
1. To understand the characteristics of a RC series network in ac circuit.
2. To understand the capacitive reactance, impedance, and phase angle.
Theory of operation
When an ac voltage is applied across a pure resistance, the resultant current is in
phase with the applied voltage. Resistance therefore has no phase angle associated
with it and impedance of resistor is simply written as R<0°. When an ac voltage is
applied across a pure capacitor, the resultant current leads the voltage by 90°.
Capacitance therefore has a phase angle associated with it. The opposition that a
capacitor offers to the flow of alternating current is called capacitive reactance Xc and
the impedance of a capacitor is written as Zc = Xc< -90°, or -jXc. The magnitude of Xc is
Xc = 1/(2TfC) = 1/wC. It implies, the impedance of capacitor is,
An RC series circuit with an ac supply voltage is shown below circuit. The impedance of
this circuit can be expressed as
ZT = ZR + Zc = R<0° + Xc<-90°
The current in the circuit is
Zc = = < (-90°)

The voltage across C is

By Kirchchoff's voltage law, then
