In any electrical installation, some current will flow through the protective ground conductor to ground. This is usually called leakage current. Leakage current most commonly flows in the insulation surrounding conductors and in the filters protecting electronic equipment around the home or office.
Also to know is, what is the leakage current of diode?
Reverse leakage current in a semiconductor device is the current from that semiconductor device when the device is reverse biased. Hence it is also called as reverse saturation current. The term is particularly applicable to mostly semiconductor junctions, especially diode and thyristor.
What is leakage current in a PN junction diode?
The applied reverse bias attracts majority carriers away from the junction. This increases the thickness of the nonconducting depletion region. Reverse biased PN junctions show a temperature dependent reverse leakage current. This is less than a µA in small silicon diodes.
