The equation for the dissipation factor is the series resistance divided by the capacitive reactance or shown as DF = Rs/Xc. Another term that you may see more is the Q factor or quality factor. The Q factor is the mathematical reciprocal of the dissipation factor; as DF decreases QF increases.

What is meant by dissipation factor?

Dissipation factor is defined as the reciprocal of the ratio between the insulating materials capacitive reactance to its resistance at a specified frequency.

What is dissipation factor and quality factor?

In physics, the dissipation factor (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of quality factor, which represents the "quality" or durability of oscillation.
