Capacitors
Whenever power (energy) in the form of voltage times current is applied to a capacitor, part of that total power is used or "lost" within the capacitor itself. The ratio of this "power loss" to the total power supplied is the "power factor" (PF) of the capacitor. This PF figure ...

However, if there are hundreds of capacitors, it is tedious to remove each capacitor, and there is an increased risk of damaging the capacitors or the circuit board during the removal. A typical ESR meter uses a high-frequency current of about 100 kHz and a low voltage of about 250 mV or less.
Dissipation factor
The loss tangent is defined by the angle between the capacitor''s impedance vector and the negative reactive axis. If the capacitor is used in an AC circuit, the dissipation factor due to the non-ideal capacitor is expressed as the ratio of the resistive power loss in the ESR to the reactive power oscillating in the capacitor, or
