The impedance z of a parallel rc circuit is similar to that of a parallel rl circuit and is summarized as follows. Z is obtained by dividing v by i. A first order rc circuit is composed of one resistor and one capacitor and is the simplest type of rc circuit.
Voltage drops in a parallel rc circuit are the same hence the applied voltage is equal to the voltage across the resistor and voltage across the capacitor.
How the formula is applied. The angle θ of z is obtained by subtracting the angle of the current i from the angle of the voltage v. The circuit current will have a phase angle somewhere between 0 and 90. Current in a parallel r c circuit is the sum of the current through the resistor and capacitor.
