Wheatstone bridge Principle The Wheatstone bridge circuit is used to determine unknown resistances. The total resistance of resistors connected in parallel and in series is measured. Benefits - Highly precise and reproducible measurements possible
- Many different measurement variations possible
- Also suitable for measurement of low resistances
Tasks - Determination of unknown resistances.
- Determination of the total resistance of resistors in series and of resistors in parallel.
Learning objectives - Kirchhoff's laws
- Conductor
- Circuit
- Voltage
- Resistance
- Parallel connection
- Series connection
