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 202resistance is connected across BD. Use Thevenin's theorem to compute the current through the galvanometer when a p.d. of 10 V is maintained across AC. (Elect. Technology, Vikram Univ. of Ujjain) CamScanner aU a 120 Electrical Technology II Solution. (i) When galvanometer is removed from Fig. 2.139 (a), we get the circuit of Fig. 2.139 (b). (ii) Let us next find the open-circuit voltage V (also called Thevenin voltage V) between points B and D. Remembering that ABC (as well as ADC) is a potential divider on which a voltage drop of 10 V takes place, we get
