ineed answer Example 2.66. The four arms of a Wheatstone bridge have the following resistances:AB = 100, BC = 10, CD = 4, DA = 502. A galvanometer of 20 2 resistance is connected acrossBD. Use Thevenin's theorem to compute the current through the galvanometer when a p.d. of 10 Vis maintained across AC.(Elect. Technology, Vikram Univ. of Ujjain)CamScanner a Wa pual120Electrical TechnologySolution. (i) When galvanometer is removed from Fig. 2.139 (a), we get the circuit ofFig. 2.139 (b).(ii) Let us next find the open-circuit voltage V (also called Thevenin voltage V) betweenpoints B and D. Remembering that ABC (as well as ADC) is a potential divider on which a voltagedrop of 10 V takes place, we get
