6 FAQs about [Reactance characteristics of capacitors]
What is the capacitive reactance of a capacitor?
Capacitive reactance is a complex number with a phase angle of -90 degrees. I hope this helps! The two factors that determine the capacitive reactance of a capacitor are: Frequency (f): The higher the frequency of the AC signal, the lower the capacitive reactance.
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 does capacitive reactance affect frequency?
As frequency increases, capacitive reactance decreases. This behaviour of capacitor is very useful to build filters to attenuate certain frequencies of signal. Capacitive reactance is also inversely proportional to capacitance. Capacitance and capacitive reactance both changes when multiple capacitors are introduced to the existing circuit.
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.
Why do AC circuits suffer from 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. Like resistance, reactance is also measured in Ohm’s but is given the symbol X to distinguish it from a purely resistive value.
What is the AC impedance of a capacitor?
The AC impedance of a capacitor is known as Reactance and as we are dealing with capacitor circuits, more commonly called Capacitive Reactance, XC Capacitance in AC Circuits Example No2. When a parallel plate capacitor was connected to a 60Hz AC supply, it was found to have a reactance of 390 ohms.
