☆ state and explain wheatstone Bridge
=>
Wheatstone Bridge which is also known as resistance bridge. It is used to calculate the unknown resistance of the circuit by balancing the two leg of bridge circuit. This circuit have two known resistors those resisitor are unknown resistor and variable resistor which are connected in the form of a bridge. The ratio of the two resistance (R1/R3) in the one edge is equal to the ratio of the two resistance (R4/R2) in another edge of the circuit. then there will be no flow of current(I) between the midpoints of the two edges of resistance in the circuit.
A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component.
hope it will help you ❤️❤️
