What is meant by ground in electronics?

“Ground” has become an everyday term in electronic and electrical circuits that it is even used electronic devices with no contact with the earth the ground plane on the PCB or in a circuit (with reference to which all the voltages on the PCB are assessed) is known as the ground in the circuit. This is a great method of linking the circuit’s ground symbol.

The voltage is a variable quantity. To determine the voltage of one spot, a reference is required to be chosen to test against. This reference point commonly known as “ground” and is considered to be at zero voltage. To ensure safe voltage levels or an enclosed enclosures, this is not required to be considered Earth ground. There could multiple ground circuit, because of the finite conductivity in wires.
