With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
Now we will combine the two components together in series form and investigate the effects. Series capacitor circuit: voltage lags current by 0° to 90°. The resistor will offer 5 Ω of resistance to AC current regardless of frequency, while the capacitor will offer 26.5258 Ω of reactance to AC current at 60 Hz.
You will recall that a series circuit provides only one route for the current to flow between two points in a circuit, so for example the diagram below shows a resistor in series with a capacitor between the points A and B. The total impedance (resistance) of this circuit is the contribution from both the capacitor and resistor.
In the previous parallel circuit we saw that the total capacitance, CT of the circuit was equal to the sum of all the individual capacitors added together. In a series connected circuit however, the total or equivalent capacitance CT is calculated differently.
The combination of a resistor and capacitor connected in series to an AC source is called a series RC circuit. Figure 1 shows a resistor and pure or ideal capacitor connected in series with an AC voltage source. The current flow in the circuit causes voltage drops to be produced across the capacitor and the resistor.
The relationship between the current and voltages in a series RC circuit is illustrated in the vector (phasor) diagram of Figure 2 and can be summarized as follows: The applied source voltage and current will be out of phase by some amount between 0 and 90 degrees.
