What is a Ground Loop? (Electronics/Electrical)
In: 1
Ground is important for safety in electrical circuits
Ground is important in electronic circuits as a drain for “noise” (spurious signals)
Both types of systems should share a single ground point. When one or more ground points are introduced to the circuit they may have different potentials. Current will begin to flow between the multiple grounds creating a ground loop.
Ground loops create noise/interface in electronics (to the point of damage in some cases); and ground loops in electrical circuits can be dangerous
