Wheatstone Bridge is a simple circuit that is used for accurately measuring the value of an unknown resistor. It consists of four resistor and a galvanometer two resistors have fixed values, one is variable resistor the 4th one is an unknown resistor by adjusting the value of the variable resistor. resistor we can calculate the value of unknown resistor. at null resistor the potential drop across the resistors becomes equal and the flow of current through galvanometer becomes stop at that point we can measure the value of unknown resistor by solving the equations. • #wheatstonebridge #electronic #physics #currentandelectricity
