## How do you calculate inductor 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.

### How do you find the resistance of an inductor?

The opposition of an inductor to a change in current is expressed as a type of AC resistance. I=VXL I = V X L , where V is the rms voltage across the inductor.

#### At what frequency will a 2h inductor have a reactance of 4000 ohm?

9. At what frequency will a 2 H inductor have a reactance of 4000 22? Ans. (1000/1) Hz.

**What is the formula of reactance?**

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. L= the inductance value of coil in henries….

**What is the resistance of an inductor?**

zero

The resistance of an ideal inductor is zero. The reactance of an ideal inductor, and therefore its impedance, is positive for all frequency and inductance values. The effective impedance (absolute value) of an inductor is dependent of the frequency and for ideal inductors always increases with frequency.

## What inductance will give the same reactance as a capacitor of 2 microfarad when both are at 50 hertz?

What inductance will give the same reactance as a capacitor of 2 µF when both are at 50 Hz? => L=5H.

### Why is capacitive reactance measured in ohms?

As the frequency applied to the capacitor increases, its effect is to decrease its reactance (measured in ohms). Likewise as the frequency across the capacitor decreases its reactance value increases. This variation is called the capacitor’s complex impedance.

#### What is the reactance of an inductor at high frequency?

The slope shows that the “Inductive Reactance” of an inductor increases as the supply frequency across it increases. Then we can see that at DC an inductor has zero reactance (short-circuit), at high frequencies an inductor has infinite reactance (open-circuit).

**What is the inductive reactance of a 55MH coil?**

Example: An inductor of 55mH, has a frequency of 50Hz, which is its inductive reactance, to find the answer it must be multiplied: 2xπx50x55x10 ^ -3 = 17,28Ohm A coil has an inductance of 0.5H. What will be the value of the inductive reactance, if the coil has a frequency of 100Hz?

**How do you calculate the inductive reactance of a 800hz circuit?**

RTA: // The inductive reactance knowing that the frequency is 800Hz is calculated as follows: 2xπx240x10 ^ -9 × 10000 = 0.02 Ohm. an 8H inductor is connected to a circuit at a frequency of 60Hz.

## What is the formula for inductance?

Inductive Reactance: Inductive Reactance: Frequency: Inductance: where, X L = Inductive Reactance, f = Frequency, L = Inductance.
