An example would be (X_L = j68 Omega). As stated, while a resistance cannot be added directly to a reactance, reactances can be added together so long as we heed the signs. For example, if we have a capacitive reactance of (−j60 Omega) in series with an inductive reactance of (j100 Omega), the result is (j40 Omega). This is due to
Capacitive reactance opposes the flow of current in a circuit and its value depends on the frequency of the applied voltage and the capacitance rating of the capacitor.

Series capacitors are installed in series with transmission lines. In effect, they cancel a portion of the series reactance of transmission lines, thus reducing the electrical length of the line.

Capacitance in AC Circuits – Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only. Like resistance, reactance is also measured in Ohm''s but is given the symbol X to distinguish it from a purely resistive value. As reactance is a quantity that can also be applied to Inductors as well as Capacitors, when used with capacitors
Perhaps the first practical issue we face is determining the effective impedance of an RLC series loop. For starters, resistors in series simply add.

We can calculate the reactance of a capacitor at any particular frequency using the expression: where C is the capacitance in farads and f is the frequency. We can see from this that the magnitude of the reactance of a capacitor decreases proportionally with frequency. But hold on! Capacitors are more than ‘frequency-dependent resistors’.
Then to summarise, the total or equivalent capacitance, CT of a circuit containing Capacitors in Series is the reciprocal of the sum of the reciprocals of all of the individual capacitance’s added together.
A capacitor with a sinusoidal voltage of frequency f across it will have a sinusoidal current flowing through it. The ratio of the voltage to the current is known as the ‘reactance’ of the capacitor at frequency f. The situation is analogous to that with a resistor, and the unit of reactance is again ohms. And Ohm's Law again applies:
