Capacitors are called to be connected in series if the there is only one path for the flow of current. Resistors are said to be connected together in parallel when both of their terminals are respectively connected to each terminal of the other resistor or resistors.

Resistor and capacitor in parallel because the power source has the same frequency as the series example circuit and the resistor and capacitor both have the same values of resistance and capacitance respectively they must also have the same values of impedance.
Resistor and capacitor connected in parallel. Or if the head of the second capacitor is connected to the tail of first it is called series combination as shown in the following circuit. C is the capacitance in farads. To calculate the total impedance resistance of this circuit we again use the capacitative reactance xc as the equivalent resistance of the capacitor.
The voltage across the capacitor has a phase angle of 106750 exactly 900 less than the phase angle of the circuit current. Then we use the same rules introduced for summing resistors. F is the frequency in hz.
Notice how the voltage across the resistor has the exact same phase angle as the current through it telling us that e and i are in phase for the resistor only. Individual resistors can be connected together in a series connection a parallel connection or combinations of both series and parallel together. Series combination of resistors.
This results in a more complex circuit whose total circuit resistance is a combination of the individual resistors. The figure below shows a parallel combination of a single resistor and capacitor between the points a and b. The complex impedance z real and imaginary or resistance and reactance of a capacitor and a resistor in parallel at a particular frequency can be calculated using the following equations.
R is the resistance in ohms.
