What is Wheatstone Bridge? Circuit, Theory, Principle & …
Hence, the value of unknown resistance is calculated through this formula, given that current through Galvanometer is Zero. So we need to adjust the potentiometer till the point when voltage at C and D will be equal, in that condition current through point C and D will be zero and the Galvanometer reading will be Zero, in that particular position Wheatstone Bridge will be called in Balanced

Deep Well Anode System Design | Matcor, Inc.
Dwight’s Model Preserved – Groundbed resistivity more closely approximates Dwight’s model because the actual anode length is the entire length of the active area. 5. Longevity – MATCOR’s system has a longer operating life because of the use of MMO anode and the reduced groundbed stress caused by multiple individual anodes all operating independently and at different outputs.
