2. Energy can only be transferred from one form to another.
3. The device which converts energy from one form to another is called a transducer.
4. A microphone with the help of transducer converts sound energy into electrical energy.
5. On the other hand, a buzzer converts electrical signals or energy into sound energy.
6. Hence the given statement is true.
