As stated in another post, the Earth is in fact NOT at the same potential everywhere, if you measure “ground” at power equipment any distance appart, you might find supprising differences in potential, and thus suprising (and possibly dangerous) currents if you assume they are all the same. Grounded mats (referred to as ESD mats), grounded chairs, and wrist straps provide adequate ESD protection for your ICs by grounding you—thus discharging any static you may have on your body—prior to touching any sensitive components.

This philosophy builds on the theory that all voltages in a circuit are referred to a single ground point. You can verify this point by measuring the resistance between the ground terminals of any two pieces of test equipment. If it is not, the measurement is meaningless. Export. Planting Seeds. Media/News Company. Connecting these ALSO to the earth makes them deliberatly at the same local potential as the Earth, so you are less likely to become a fault path for current if you happen to be touching the equipment and there is a fault through the earth, and for somewhere deliberate for current to go if it gets a near hit by lightening.
