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. WebWheatstone bridge is an electric circuit that is used to measure an unknown resistance by balancing two legs of the circuit. The circuit is used to provide accurate measurements. Wheatstone bridge consists of four arms (R 1, R 2, R 3, and R 4) of which two arms have known resistances.The other two arms consist of an unknown resistance and a variable …
