## Q Factor Formula

The following equation is used to calculate the q factor of a resonator.

Q= X / R

- Q = quality factor
- X = reactance (ohms)
- R = the resistance (ohms)

## Q Factor Definition

A Q Factor is the ratio of reaction to resistance of an electrical component. It’s used to measure the quality of an electrical component with respect to the transmittance of electrons.

## Q Factor Example

How to calculate a q factor?

**First, determine the reactance.**Calculate the total reactance of the component.

**Next, determine the resistance.**Measure the total resistance of the component.

**Finally, calculate the Q factor.**Calculate the Q factor using the equation above.

## FAQ

**What is a q factor?**

The q factor, also known as quality factor, is a measure of the ratio of reactance to resistance of a capacitor/electronic component. As it sounds, it’s a measure of the quality of the component.

**What is reactance?**

Reactance is a measure of a capacitors ability to conduct electricity.
