The influence of voltage burden on the detection of bridge balance may be overlooked as people may simply believe that a null current represents a bridge balance. In this study, the influence is investigated, and the measures for minimising the influence are introduced. A method for determining both the resistance ratio and voltage burden is also proposed.
