What is inductive reactance

Inductive reactance is defined as:(10-4)XL=_ωL=2πfLwhere XL is the inductive reactance, ω is the angular frequency, f is the frequency in Hertz, and L is the inductance. From: Linear Circuit Design Handbook, 2008.

What is inductive and capacitive 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.

What is inductive reactance SI unit?

Inductive reactance is denoted as XL. The SI unit is the ohm.

What is the inductive resistance?

Inductive reactance is the resistance offered by the inductive circuit. It is the opposition to a changing current flow offered by an inductor. The SI unit for it is Ohm(Ω). The inductive reactance formula is: Inductive reactance(XL) : 2π f L.

What is the unit of inductance?

The SI unit of inductance is Henry abbreviated as 'H'. It is defined as the measure of electric current changes at one ampere per second, resulting in an electromotive force of one volt across the inductor. Henry is a derived unit based on some 7 base SI units like metre (m), second (s), kilogram (kg), and ampere (A).

What is the symbol for inductive reactance?

Inductive Reactance which is given the symbol XL, is the property in an AC circuit which opposes the change in the current.

What is called capacitive reactance?

The measure of the opposition to alternating current by the capacitor is called Capacitive Reactance. The unit of Capacitive Reactance is Ohms like resistance. The symbol of Capacitive Reactance is XC .

Why it is called reactance?

Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance. In some respects, reactance is like an AC counterpart of DC (direct current) resistance.

What is XC and XL?

Xc = Capacitive Reactance, in Ohms. • Xl = Inductive Reactance, in Ohms. • R = Resistance, in Ohms.

What is reactance formula?

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

Why is the unit of inductive reactance is ohm?

The inductive reactance is directly proportional to frequency. The unit of Inductive reactance is Ohm. The capacitive reactance is inversely proportional to the frequency. The unit of Capacitive reactance is Ohm.

What is unit of XC?

The unit of Capacitive Reactance Xc is Ohm.

What causes inductive reactance?

Inductive reactance is caused by devices in which wire is wound circularly — such as coils (including line reactors), chokes, and transformers. Reactance that occurs in a capacitor is known as capacitive reactance.

What is the unit for reactance?

Reactance is mathematically symbolized by the letter “X” and is measured in the unit of ohms (Ω).

What is XL and XC in RLC circuit?

In a series RLC circuit at resonance, the two reactances, XL and XC are equal and canceling. In addition, the two voltages representing VL and VC are also opposite and equal in value, thereby canceling each other out.

What is the SI unit of impedance?

The unit of impedance, like that of resistance, is the ohm.

What is the SI unit of resistance?

The SI unit of electric resistance is the ohm (Ω). 1 Ω = 1 V/A.

What is the formula of inductor?

V=L di/dt, according to the inductor equation. This states that the voltage across an inductor is proportional to the current through the inductor's rate of change.

Why do inductors block AC?

Since AC varies both in magnitude and direction, its flow is opposed in L. For an ideal inductor of zero ohmic resistance, the back emf is equal and opposite to the applied emf. Therefore L blocks AC.

What is reactance in RLC circuit?

The reactance of inductor L = XL = ωL and its impedance Zi = 0 + jωL = 0 + jXL. Thus, the impedance of an inductor is always imaginary, leading the resistor R by 90◦. Curve (a) in Figure 12.7 shows the variation of XL( = ΩL) with the frequency.
