What is a Wheatstone Bridge Circuit?Wheatstone Bridge DefinitionA Wheatstone Bridge is widely used to measure electrical resistance accurately. It includes two known resistors, one variable resistor, and one unknown resistor connected in a bridge form. By adjusting the variable resistor until the galvanometer reads zero current, the ratio of the known resistors matches the ratio of the variable resistor and the unknown resistor. This allows easy measurement of the unknown electrical resistance.W
