Ground

maker

Ground refers to a reference point in an electrical circuit from which voltages are measured.

expanded

In electrical circuits, the term 'ground' signifies a common return path for electrical current, providing a reference point for all voltages in the system. Grounding ensures safety and functionality by minimizing voltage differences and preventing static electricity build-up. It is critical for the operation and protection of electrical and electronic equipment.

examples

In residential electrical systems, the main electrical panel usually has a ground bus bar connected to a physical ground rod driven into the earth.

Commonly used in residential and commercial buildings to ensure electrical safety and system stability.

In a PCB (Printed Circuit Board), a ground plane is used to provide a common return path and reduce electromagnetic interference (EMI).

Used in electronic devices, such as microcontrollers or RF transmitters, where stable operation is crucial.
