Figure 1 resistor bridge circuit with 25 volt source potential. The resulting circuit may be used to determine the potential and current through r5 upon inserting this element into the thevenin equivalent circuit. Bridge circuits rely on sensitive null voltage meters to compare two voltages for equality.
Analysis of the circuit shows that when r 2 is adjusted so that the ammeter reads zero current the resistance of both arms of the bridge circuit is the same.
Analysis of the circuit shows that when r 2 is adjusted so that the ammeter reads zero current the resistance of both arms of the bridge circuit is the same. The wheatstone bridge circuit is nothing more than two simple series parallel arrangements of resistances connected between a voltage supply terminal and ground producing zero voltage difference between the two parallel branches when balanced. Short circuit the s c current is step 3. Analysis of the circuit shows that when r 2 is adjusted so that the ammeter reads zero current the resistance of both arms of the bridge circuit is the same.
