Which of the following is a transducer?
- A Loud speaker
- B Amplifier
- C Receiver
- D Transmitter
Answer & Solution
Correct Answer
(A) Loud speaker
Step-by-step Solution
Detailed explanation
A loud speaker converts electrical energy into sound energy (mechanical vibrations). Amplifiers, receivers, and transmitters are complex electronic systems that process signals but do not inherently serve the primary function of energy conversion across different forms.
