What is an Electrical Ground?
An electrical ground is a reference point built into the electrical circuit, used as a baseline when measuring other electrical currents. It also serves as the return path for an electric circuit. The purpose of an electrical ground is to allow any spikes in electricity to be directly away from the electric circuit and into the ground where it is harmlessly absorbed. An electrical circuit is designed to carry electricity, regardless of the form. Static electricity can build up in a circuit through poor insulation and create a dangerous situation, where the circuit is overloaded with electricity. The electrical ground is the escape route for this additional energy and is built into most electric devices. Electric ground is a term that is used in airplanes and on boats, where there is no connection to the ground. In Great Britain, the term used is earth or earthing to indicate that an electrical circuit is ground. In the installation of mains electricity, an electrical ground describes a
