What is capacitor reactance?
Capacitive reactance can be thought of as a variable resistance inside a capacitor being controlled by the applied frequency. Unlike resistance which is not dependent on frequency, in an AC circuit reactance is affected by supply frequency and behaves in a similar manner to resistance, both being measured in Ohms.
What is capacitive reactance?
Capacitive reactance is the opposition presented by a capacitor to the flow of alternating current (AC) in a circuit. Unlike resistance, which remains constant regardless of frequency, capacitive reactance varies with the frequency of the AC signal. It is denoted by the symbol XC and is measured in ohms (Ω).

How do you add capacitive reactance to a circuit?
This is done by adding capacitive reactance to a circuit when the total reactance is inductive. If the total reactance is capacitive, inductive reactance is added in the circuit. ANSWERS TO QUESTIONS Q1. THROUGH Q31.
Why does a capacitor have a resistance and reactance?
A capacitor has both resistance and reactance, therefore requiring complex numbers to denote their values. Reactance in capacitor is created due to current leading the voltage by 90°. Normally the current and voltage follows Ohm's law and are in phase with each other and vary linearly.
Which direction should a capacitive reactance be drawn?
When you have a capacitive reactance to deal with instead of inductive reactance as in the previous example, it is customary to draw the line representing the capacitive reactance in a downward direction. This is shown in figure 4-6.
