Difference Between Resistance and Reactance

Mathematically, resistance is simply voltage divided by current. Reactance is a property that opposes a change in current and is found in both inductors and capacitors. Because it only affects changing current, reactance is specific to AC power and depends on the frequency of the current.

Key Differences Between Resistance and Reactance

The resistance is the obstacle in the flow of current in an electrical circuit due to resistor. While reactance is the opposition to the charging current due to either inductor or capacitor. Resistance is the property associated with both ac and dc circuit.

What is called reactance?

In electric and electronic systems, reactance is the opposition of a circuit element to the flow of current due to that element's inductance or capacitance. ... As frequency increases, inductive reactance also increases and capacitive reactance decreases.

What's the difference between resistance and impedance?

Impedance- The main difference between Resistance and Impedance is their behavior to AC and DC currents. While resistance controls the flow of AC and DC current, Impedance just determines the alternative current flow. It means that impedance is only used in AC systems and does not have any use in DC diagrams.

What is difference between inductance and reactance?

Inductance is a physical property of the coil or conductor, units in Henries, and is independent of the frequency of the signal in the component. Reactance, in units of Ohms, is dependent on the frequency of the signal.

What is a resistance?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). ... All materials resist current flow to some degree.

Is inductive reactance the same as resistance?

Inductive reactance is the name given to the opposition to a changing current flow. This impedance is measured in ohms, just like resistance. In inductors, voltage leads current by 90 degrees.

What is reactance formula?

Reactance formula

Xc is infinite for steady DC, at zero frequency (f=0Hz). ... Inductive reactance, or XL, is a product of 2 times p (pi), or 6.28, frequency of the ac current in hertz, and the inductance of the coil, in henries. XL =2p x f x L. L= the inductance value of coil in henries.

What is reactance function?

Reactance, in electricity, measure of the opposition that a circuit or a part of a circuit presents to electric current insofar as the current is varying or alternating. Steady electric currents flowing along conductors in one direction undergo opposition called electrical resistance, but no reactance.

Can reactance be negative?

Resistance is always positive, while reactance can be either positive or negative.

What causes impedance?

the resistance is caused by the collisions of the electrons with the atoms inside the resistors. the impedance in a capacitor is caused by the creation of an electric field. the impedance in an inductor is caused by the creation of a magnetic field.

What is the impedance of capacitor?

The impedance of an ideal capacitor is equal in magnitude to its reactance, but these two quantities are not identical. Reactance is expressed as an ordinary number with the unit ohms, whereas the impedance of a capacitor is the reactance multiplied by -j, i.e., Z = -jX.
