What is a capacitor reactance?
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. The reactance is calculated to determine the impedance of a circuit, which is a measure of the total opposition to the flow of current in the circuit.
What factors determine the capacitive reactance of a capacitor?
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. This is because at higher frequencies, the capacitor charges and discharges more rapidly, reducing its opposition to current flow.
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).
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.
How does frequency affect capacitive reactance?
As the frequency of the AC current increases, the capacitive reactance decreases, allowing more current to flow through the capacitor. Conversely, as the frequency decreases, the capacitive reactance increases, limiting the current flow.
How does capacitor reactance affect voltage and current?
In AC circuits, capacitor reactance leads to a phase shift between voltage and current. Unlike resistive elements where voltage and current are in phase, capacitors exhibit a 90-degree leading phase shift, making them essential for power factor correction and voltage regulation.
