The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate. Variations on the Wheatstone bridge can be used to measure capacitance, inductance, impedance and other quantities, such as the amount of combustible gases in a sample, with an explosimeter. … 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. The primary benefit of the circuit … See more Quick derivation at balance At the point of balance, both the voltage and the current between the two midpoints (B and D) are zero. Therefore, $${\displaystyle I_{1}=I_{2}}$$, $${\displaystyle I_{3}=I_{x}}$$, See more • Electronics portal • Diode bridge, product mixer – diode bridges • Phantom circuit – a circuit using a balanced bridge • Post office box (electricity) See more In the figure, Rx is the fixed, yet unknown, resistance to be measured.
