Prof. Filippo Capolino ECE Dept. Fall 2006 Notes 5 ECE 2317 ECE 2317 Applied Electricity and Magnetism Applied Electricity and Magnetism Notes prepared by the EM group, University of Houston . (used by Dr. Jackson, spring 2006) Grounding Grounding Grounding: connecting a conductor to the physical earth • Safety reasons • Noise reasons equipment water pipe Grounding (cont.) Grounding (cont.) • Ensures that there is no voltage drop between equipment and ground • Ensures that the is no electric field outside of equipment • Ensures that there is no charge build up on equipment equipment water pipe + - V AB = 0 Grounding (cont.) Grounding (cont.) equipment ground Ground symbol: Note: grounding is NOT is the same thing as a reference point. (However, when a circuit is grounded, the ground is OFTEN chosen as a reference point of zero volts.)
