Classification
Nouns denoting man-made objects.
Examples
- The bridge circuit is commonly used to measure unknown resistances by balancing two legs of a bridge circuit, one leg containing the unknown resistance.
- A bridge circuit is used to measure the resistance of the strain gauge by converting the change in resistance to a voltage.
- The Wheatstone bridge circuit is a type of bridge circuit that is used to measure electrical resistance by balancing two legs of a bridge circuit.
- The op-amp bridge circuit is a variation of the Wheatstone bridge circuit that uses an operational amplifier to amplify the output voltage.
- In a bridge circuit the ratio of the two resistances defines the voltage division of the differential amplifier.
