Answer 2

The correct answer is option (a) active transducer.

• A transducer that converts a number of non-electronic objects into an electric field is known as an active transducer. The best conditions for non-electric values ​​are temperature, pressure, and light.
• An active transducer is a type-generating transducer that can generate electrical or current output without using any external power source.
• These transducers draw the required energy for their performance in the measurement system. It is noteworthy in the case of active transducers that the output is very small; therefore, additional amplification is required in its case.
