As a result of the loss of useful energy in a simple circuit with a resistor and an ideal (perfect) capacitor, equivalent series resistance (ESR) is known as internal resistance.A capacitor's dissipation factor determines how much power is lost when AC is applied through it, and its dissipation factor is 4 %.The Tan Delta is a dielectric test on the insulating oil to determine its quality, and it is 0.04.
