How do you find the reactance of an inductor?

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.

What value of inductance should be used if a 20.0 Kω reactance is needed at a frequency of 500 Hz?

6.37 henries
Calculator Screenshots So the inductance then is the reactance— 20.0 times 10 to the 3 ohms— divided by 2π times the frequency of 500 hertz, which is 6.37 henries.

What is reactance formula?

Reactance formula The total reactance (X) is equal to the difference between the two: Total Reactance, X =XL – Xc. a. Capacitive Reactance Xc. The reactance, which is large at low frequencies and small at high frequencies is known as capacitive reactance (Xc).

How do you calculate total reactance?

Subtract inductive and capacitive reactance to get total reactance. Because one of these effects increases as the other decreases, these tend to cancel each other out. To find the total effect, subtract the smaller one from the larger. Calculate impedance from resistance and reactance in series.

What is reactance of an inductor What is unit of reactance?

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. Capacitive reactance has units of ohms. (The unit of capacitance is farad.)

At what frequency will have 100μf capacitor has a reactance of 100ω?

A coil has reactance of 100Ω when the frequency is 50 Hz .

What is capacitive reactance formula?

The formula for calculating the Capacitive Reactance, or impedance of a capacitor is: Capacitive reactance, denoted as x sub c (XC), is equal to the constant one million (or 106) divided by the product of 2p ( or 6.28) times frequency times the capacitance . where: XC = Capacitive reactance measured in ohms.

What is reactive capacitance?

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.

How do you calculate reactive power from 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.
