Enter the reactance and resistance of a coil or capacitor into the calculator to determine the Q factor, also known as the quality factor.

## 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 the 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?

1. First, determine the reactance.

Calculate the total reactance of the component.

2. Next, determine the resistance.

Measure the total resistance of the component.

3. Finally, calculate the Q factor.

Calculate the Q factor using the equation above.
