WebDefinitions. Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low-impedance path to the earth to prevent hazardous voltages from appearing on equipment (high voltage spikes). [citation needed] The terms ground and earth are used synonymously in this section; ground is more common in North … WebFeb 2, 2024 · Signal ground is merely a reference point; the important issue is the current path. In other words, the signal needs a return path independent of any other currents. Chassis ground should only be used to prevent the chassis from wandering around, and its main purpose is shielding. No current should flow in the chassis.
