Description
In this project we find the unknown value of resistor using Wheatstone bridge. In this project we use small voltmeter with four resistance. Out of the four resistors one resistor is unknown and one resistor is variable. First we connect unknown resistor and vary the knob of variable resistor to set the meter for zero value. When meter is on zero value then Wheatstone bridge is balanced and we check the variable resistor pointer. Variable resistor pointer shows the value of unknown resistor.
