The Wheatstone Bridge
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
A Wheatstone bridge is an instrument that measures an unknown electrical resistance. This is accomplished by balancing the two legs of the circuit, with one of them containing the unknown resistor . When the bridge is perfectly balanced, the voltage across the galvanometer is zero and therefore no current flows between the midpoints. This Demonstration allows you to visualize the Wheatstone bridge circuit and to determine the unknown resistance by changing the resistance of variable resistor .
