Capacitor quality factor (Q factor)

This parameter quantifies the ratio of the energy stored in the capacitor to the energy dissipated over one cycle of operation. A higher Q-factor indicates lower energy losses and improved efficiency in energy storage and release. Additionally, the Q factor is a dimensionless parameter, meaning it has no units. Figure 1 illustrates how the quality factor of …

Capacitor in Electronics – What It Is and What It Does

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
