Piezo-electric transducers are devices that are used to convert mechanical energy into electrical energy. These transducers are capable of measuring various physical quantities, including force, pressure, and sound. In this question, we are asked to identify which of the following can be measured using a Piezo-electric transducer.

Measurement Using Piezo-electric Transducer:

The correct answer is option C, which is force. Below are the reasons why Piezo-electric transducers can measure force:

- Principle of Operation: Piezo-electric transducers work on the principle of the piezoelectric effect. This effect occurs when certain materials, such as quartz, generate an electrical charge in response to mechanical stress. When a force is applied to the transducer, it generates a voltage output that is proportional to the force applied.
- Sensitivity: Piezo-electric transducers are highly sensitive to force and can measure even small changes in force. This makes them ideal for applications where high accuracy is required.
- Dynamic Range: Piezo-electric transducers have a wide dynamic range, which means that they can measure both small and large forces accurately.
- Frequency Response: Piezo-electric transducers have a high frequency response, which means that they can measure rapidly changing forces. This makes them suitable for applications such as impact testing and vibration analysis.

Conclusion:

In summary, Piezo-electric transducers can measure force, not velocity, displacement, or sound. They are highly sensitive, have a wide dynamic range, and a high frequency response, making them ideal for applications such as impact testing, vibration analysis, and force measurement in various industries.
