Question

what is leakage current?And how doest it occur​

Answer 1

Answer:

In electronics, leakage is the gradual transfer of electrical energy across a boundary normally viewed as insulating such as the spontaneous discharge of a charged capacitor, magnetic coupling of a transformer with other component, or flow of current across a transistor in the "off" state or a reverse-reverse-polarized diode.

Explanation:

A leakage current in equipment flows when an unintentional electric connection occurs between the ground and energized part or conductor

Answer 2

The leakage current in equipment flows when an unintentional electrical connection occurs between the ground and an energized part or conductor. ... These results into small current leaking or flowing through the through the dielectric, in the case of a capacitor.
