# What is the relationship between inductive reactance and inductance?

## What is the relationship between inductive reactance and inductance?

The inductive reactance of a component is directly proportional to the inductance of the component and the applied frequency to the circuit. By increasing either the inductance or applied frequency, the inductive reactance will likewise increase and present more opposition to current in the circuit.

## Is inductive reactance the same as inductance?

More specifically, inductive reactance (Xl) is just Inductance (L) times angular frequency (w). So if you increase the frequency of the current running through your inductor, the reactance will increase, but the inductance will stay the same.

When inductors are connected in series, the total inductance is the sum of the individual inductors’ inductances. When inductors are connected in parallel, the total inductance is less than any one of the parallel inductors’ inductances.

### How do you find inductive reactance in parallel?

Parallel Aiding Inductors If the two inductances are equal and the magnetic coupling is perfect such as in a toroidal circuit, then the equivalent inductance of the two inductors in parallel is L as LT = L1 = L2 = M.

### What happens when inductive reactance is equal to capacitive reactance?

When the inductive and capacitive reactances are equal, a number of things happen: This condition is known as resonance. Both the inductive and capacitive reactances depend on frequency, with the inductive reactance proportional to frequency and the capacitive reactance inversely proportional to frequency.

What is the difference between capacitive reactance and inductive reactance?

Inductive reactance is usually related to the magnetic field surrounding a wire or a coil carrying current. Likewise, capacitive reactance is often linked with the electric field that keeps changing between two conducting plates or surfaces that are kept apart from each other by some insulating medium.

#### What is the relationship between inductive reactance and frequency?

The inductive reactance of an inductor increases as the frequency across it increases therefore inductive reactance is proportional to frequency ( XL α ƒ ) as the back emf generated in the inductor is equal to its inductance multiplied by the rate of change of current in the inductor.

#### When two inductors are connected in parallel the equivalent inductance is?

The equivalent inductance of two inductors is 2.4H when connected in parallel 10H when connected in series.

How do you calculate parallel reactance?

Calculation of Total Current and Total Impedance First, we could calculate total impedance from all the individual impedances in parallel (ZTotal = 1/(1/ZR + 1/ZL + 1/ZC), and then calculate total current by dividing source voltage by total impedance (I=E/Z).

## What is reactance and inductance?

Reactance is the effect of that inductance at a given frequency. A clear difference because the units for each is different. Inductance is the ability to create a voltage within a conductor or a nearby conductor by changing the current flow in that the first conductor. Reactance is an opposition to a change in current.

## How does inductive reactance and capacitive reactance vary with frequency?

Capacitive reactance of a capacitor decreases as the frequency across its plates increases. Therefore, capacitive reactance is inversely proportional to frequency. Capacitive reactance opposes current flow but the electrostatic charge on the plates (its AC capacitance value) remains constant.

When inductors are in parallel the total inductance of the circuit?

Note – When inductors are in parallel, the total inductance value is always less than the smallest inductor of the circuit. In other words, when inductors are in parallel, the total inductance shrinks. It’s always less than any of the values of the inductors.

### What is the reactance of an inductor?

Inductive reactance is the reactance offered by an inductor: the greater the reactance, the smaller the current. In a dc circuit inductive reactance would be zero (short-circuit), at high frequencies an inductor has infinite reactance (open-circuit). Inductive reactance acts as an opposition to the current flow in the circuit.

### What is inductive reactance (X L)?

Inductive Reactance (X L) Definition: Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of ac current. It is represented by (X L) and measured in ohms (Ω). Inductive reactance is mostly low for lower frequencies and high for higher frequencies. It is, however, negligible for steady DC current.

What happens when resistors and inductors are mixed in parallel circuits?

• When resistors and inductors are mixed together in parallel circuits (just as in series circuits), the total impedance will have a phase angle somewhere between 0° and +90°.
