A DC bridge is an electrical circuit used to measure unknown resistances by balancing two legs of a circuit. The most common type is the Wheatstone Bridge, which consists of four resistors arranged in a diamond shape, with a galvanometer to detect the balance. When the bridge is balanced, the ratio of the known resistances can be used to calculate the unknown resistance. DC bridges are widely used in laboratory settings for precise measurements.
