6 FAQs about [Capacitor s capacitive reactance]

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).

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 the difference between capacitance and reactance in AC circuits?

For capacitors in AC circuits opposition is known as Reactance, and as we are dealing with capacitor circuits, it is therefore known as Capacitive Reactance. Thus capacitance in AC circuits suffer from Capacitive Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only.

How do you calculate capacitive reactance?

To calculate the capacitive reactance, follow these steps: Write down the capacitance of the capacitor C and the AC frequency. As we've mentioned in the previous section, capacitive reactance is a capacitor's property that opposes alternating current. The same is true for any set of capacitors that we can arrange in series or parallel.

What is the difference between resistance and capacitive reactance?

Unlike resistance which has a fixed value, for example, 100Ω, 1kΩ, 10kΩ etc, (this is because resistance obeys Ohms Law), Capacitive Reactance varies with the applied frequency so any variation in supply frequency will have a big effect on the capacitor’s, “capacitive reactance” value.

What is the difference between inductive reactance and capacitive reactance?

Inductive reactance (X L) rises with an increase in frequency, whereas capacitive reactance (X C) falls. In the RC Network tutorial we saw that when a DC voltage is applied to a capacitor, the capacitor itself draws a charging current from the supply and charges up to a value equal to the applied voltage.
