Transducers are devices that convert one form of energy into another, enabling the measurement of various physical quantities. Common examples include strain gauges and thermistors, which measure strain and temperature, respectively, by detecting changes in electrical resistance. Understanding the principles of transducers is essential for applications in fields such as engineering and physics. The discussion emphasizes the importance of recognizing the relationship between the measured quantity and the transducer's output.
