Capacitance vs. Resistance

Capacitance is the ability to store electrical charge, exhibited by capacitors, while resistance is the opposition to the flow of electric current, introduced by resistors. Capacitors store energy,

6.1.2: Capacitance and Capacitors

Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it. The current through a capacitor is equal to the capacitance times the

Capacitor

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a

Capacitive Reactance

Capacitive Reactance is the complex impedance value of a capacitor which limits the flow of electric current through it. Capacitive reactance can be thought of as a variable resistance

6 FAQs about [What is the unit of resistance of a capacitor ]

What is the difference between capacitance and resistance?

In summary, capacitance is the ability to store electrical charge, and capacitors are devices that exhibit this property. Capacitors store energy, exhibit frequency-dependent behavior, and can block DC while allowing AC to pass through. Resistance, denoted by the symbol R, is a measure of a component's opposition to the flow of electric current.

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.

What is the resistance of an ideal capacitor?

The resistance of an ideal capacitor is infinite. The reactance of an ideal capacitor, and therefore its impedance, is negative for all frequency and capacitance values. The effective impedance (absolute value) of a capacitor is dependent on the frequency, and for ideal capacitors always decreases with frequency.

What is the difference between a capacitor and a resistor?

Capacitors store energy, exhibit frequency-dependent behavior, and can block DC while allowing AC to pass through. Resistance, denoted by the symbol R, is a measure of a component's opposition to the flow of electric current. It is measured in ohms (Ω). Resistors are the most common components used to introduce resistance into a 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.

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.
