Ground Loops: What is causing that electrical noise?

WebGround loops. A ground loop is a condition in an electrical system that contains multiple conductive paths for the flow of electrical current between two nodes. Multiple paths are usually associated with the ground or 0 V-potential point of the circuit. Ground loops can result in signal noise, communications errors, or a damaging flow of ground ...
