## What is the difference between capacitive reactance and inductive reactance?

If the reactance releases energy in the form of a magnetic field, it is called inductive reactance whereas if the reactance releases energy in the form of an electric field, it is called capacitive reactance. An ideal resistor will have zero reactance, whereas ideal inductors and capacitors will have zero resistance.

## What is inductive reactance in transformer?

The effect by which the current flow of an alternating or changing current in an inductor is reduced is called its inductive reactance. When a changing current is applied to an inductor, the self-inductance gives rise to an induced voltage. …

## What is inductive and capacitive reactance?

Inductive reactance is usually related to the magnetic field surrounding a wire or a coil carrying current. Likewise, capacitive reactance is often linked with the electric field that keeps changing between two conducting plates or surfaces that are kept apart from each other by some insulating medium.

## How do you calculate capacitive and inductive reactance?

This resultant is called REACTANCE; it is represented by the symbol X; and expressed by the equation X = XL − XC or X = XC − X L. Thus, if a circuit contains 50 ohms of inductive reactance and 25 ohms of capacitive reactance in series, the net reactance, or X, is 50 ohms − 25 ohms, or 25 ohms of inductive reactance.

## What is the relationship between inductive reactance and inductance?

The inductive reactance of a component is directly proportional to the inductance of the component and the applied frequency to the circuit. By increasing either the inductance or applied frequency, the inductive reactance will likewise increase and present more opposition to current in the circuit.

## What is capacitive reactance?

The opposition to the flow of alternating current due to capacitance is called “capacitive reactance.” It is measured in ohms just like resistance and inductive reactance. In capacitors, the current leads voltage by 90 degrees.

## What is capacitive reactance measured in?

ohms

Capacitive reactance is measured in ohms of reactance like resistance, and depends on the frequency of the applied voltage and the value of the capacitor.

## What is the difference between inductance and inductive reactance?

Inductance is the property of a circuit to oppose any change in current and is measured in henries. Inductive reactance is a measure of how much the countering emf in the circuit will oppose current variations.

## What is capacitive reactance XC?

The unit of Capacitive Reactance Xc is Ohm. Capacitive reactance is defined as the measure of capacitor’s opposition to alternating current. It is more complex than the resistance as the value depends on the frequency of the signal passing through the capacitor.

## What is Z impedance?

Impedance (Z), in electrical devices, refers to the amount of opposition faced by direct or alternating current when it passes through a conductor component, circuit or system. Impedance is null when current and voltage are constant and thus its value is never zero or null in the case of alternating current.

## How do I calculate inductive reactance?

The formula for calculating the inductive reactance of a coil is: inductive reactance, or XL, is the product of 2 times p (pi), or 6.28, the frequency of the ac current, in hertz, and the inductance of the coil, in henries. XL =2p x f x L.
