WebAboutTranscript. Wheatstone bridge is a special circuit consisting of 5 resistors. When the resistances in the adjacent arms have the same ratio, no current flows through the middle resistor! This is called a balanced Wheatstone bridge. It's used in calculating unknown resistances using a meter-bridge set up.
In the figure, Rx is the fixed, yet unknown, resistance to be measured. R1, R2, and R3 are resistors of known resistance and the resistance of R2 is adjustable. The resistance R2 is adjusted until the bridge is "balanced" and no current flows through the galvanometer Vg. At this point, the potential difference between … See more A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component.
