A Whitston bridge is a type of electrical circuit that can be used to measure the electrical resistance of a component. A component can be a resistor or a wire. A Wheatston bridge consists of two voltage dividers, a voltage source and a galvanometer.
The two voltage dividers have the same voltage source (and ground), while the galvanometer measures the voltage difference between the outputs of the two voltage dividers. If the current flowing in the galvanometer is zero, it means that the two voltage dividers produce the same voltage. This phenomenon can be used to measure an unknown electrical resistance by simply using simple multiplication, given that the value of the other resistors is known.
The Wheatston Bridge experiment allows you to accurately measure electrical resistance.
