What is ground for in a circuit?
What is ground for in a circuit? In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the earth. The Earth's ground is used as an electrical reference point for circuits. What is ground input? A ground-referenced signal source is connected in some way to the building ground and is, therefore, already connected to a common ground point with respect to the data acquisition (DAQ) device (assuming that the computer is plugged into the same power system.)
