What is transducer?
The device which converts the one form of energy into another is known as
the transducer.
The energy transmission may be electrical, mechanical, chemical, optical etc..
3. Where are they used and what for/Application of transducer?
1. It is used for detecting the movement of muscles
which is called acceleromyograph.
2. The transducer measures the load on the engines.
3. It is used as a sensor for knowing the engine knock.
4. The transducers measure the pressure of the gas and
liquid by converting it into an electrical signal.
5. It converts the temperature of the devices into an
electrical signal or mechanical work.
6. The transducer is used in the speaker for converting
the electrical signal into acoustic sound.
7. It is used in the antenna for converting the
electromagnetic waves into an electrical signal.

Explain what is meant by active transducer and passive transducer with an example.
Active transducers:
Active transducer is a device which converts the given non-electrical energy into
electrical energy by itself. Thermocouple, Photovoltaic cell and more are the best
examples of the transducers
Passive transducers:
Passive transducer is a device which converts the given non-electrical energy
into electrical energy by external force. Resistance strain gauge, Differential
Transformer are the examples for the Passive transducers.
