No, current flows in balanced Wheatstone bridge because: According to circuit diagram when bridge is balanced the potential at point B is equal to potential at point D. Hence two points are at same potential VB = VD Potential difference across galvanometer is zero V =VB – VD = 0 According to ohm’s Law current through galvanometer Ig = V / Rg Ig = 0 / Rg = 0 Therefore no current flows through the galvanometer and it shows zero deflection.
