Quality (Q) Factor of a Capacitor Calculator

getcalc.com's Quality (Q) Factor Calculator is an online electrical engineering tool to calculate the quality or efficiency of capacitor.

Definition & Formula

Quality Factor often called as Q factor is a dimensionless quantity to measure the quality of capacitor. It's a ratio between capacitor's reactance (Xc) and equal series resistance (ESR). It represents how efficiently the energy stored in a capacitor be used in the electrical & electronic circuits.
