Similarly, equivalent series resistance (ESR) is also known as internal resistance, as it represents the loss of useful energy in a simple electronic circuit consisting of a resistor and an ideal (perfect) capacitor.A capacitor like this leaks current 0.0005mA.Tan Delta test measures the electrical dielectric properties of insulating oil, and its tan delta is 0.04.
