#### Reactance equation

## What is reactance formula?

In inductors, voltage leads current by 90 degrees. The formula for calculating the inductive reactance of a coil is: inductive reactance, or X_{L}, 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. X_{L} =2^{p} x f x L.

## How do you calculate total reactance?

Calculate inductive reactance. This frequency is represented by the symbol ƒ, and is measured in Hertz (Hz). The full formula for calculating inductive reactance is X_{L} = 2πƒL, where L is the inductance measured in Henries (H).

## What is reactance in a circuit?

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.

## What is XL and XC in physics?

Reactance is measured in ohms ( ). There are two types of reactance: capacitive reactance (Xc) and inductive reactance (X_{L}). The total reactance (X) is the difference between the two: Total Reactance, X = X_{L} – Xc.

## What is measured in Ohm?

The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the seat of any electromotive force.

## What is inductor formula?

The inductor equation tells us: v = L d i d t v = text L,dfrac{di}{dt} v=Ldtdi. This says the voltage across an inductor is proportional to the rate of change of the current through the inductor. Since the current source provides a constant current, the rate of change, or slope, of the current is 0.

## What is resonance formula?

The resonant frequency is found from Equation 15.6. 5: f0=12π√1LC=12π√1(3.00×10−3H)(8.00×10−4F)=1.03×102Hz. At resonance, the impedance of the circuit is purely resistive, and the current amplitude is I0=0.100V4.00Ω=2.50×10−2A.

## What is difference between resistance and impedance?

It could be said that electrical resistance is the opposition to steady electric current. An ideal resistance does change with frequency when connected with DC. Impedance is the measure of the nature of opposition of the AC electricity which is created due to inductance and capacitance.

## 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 (X_{C}), is equal to the constant one million (or 106) divided by the product of 2^{p} ( or 6.28) times frequency times the capacitance . where: X_{C} = Capacitive reactance measured in ohms.

## What is difference between reactance and resistance?

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.

## What is called impedance?

Electrical impedance, measure of the total opposition that a circuit or a part of a circuit presents to electric current. Impedance includes both resistance and reactance (qq. v.).

## What is reactance of capacitor?

Capacitive Reactance is the complex impedance of a capacitor who’s value changes with respect to the applied frequency. In the RC Network tutorial we saw that when a DC voltage is applied to a capacitor, the capacitor itself draws a charging current from the supply and charges up to a value equal to the applied voltage

## What is the formula of XC?

Capacitive reactance is defined as:(10-1)Xc=1/ωC=1/2πfCwhere XC is the capacitive reactance, ω is the angular frequency, f is the frequency in Hertz, and C is the capacitance.

## How do you calculate XC and XL?

XL is called as inductive reactence and Xc is called as capacitive reactence. and the formulae[ XL = 2∏fL, XC = 1/2∏fC ] is given in that website. At resonance the reactence will be same for both cacitence and inductance.
