Answer to Question #97557 in Electrical Engineering for Ojugbele Daniel

Question #97557
A D.C wheatstone bridge has a 5.0V supply connected between A and C and a galvanometer of resistance 50ohms between point B and D what will be the current through the galvanometer when the resistance in the bridge arms are AB=120ohms, BC=120ohms, CD=120ohms, DA=120ohms.
