Q Factor Calculator

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

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.
