IPA: /trænˈsjuːdʒər/
KK: /træn'sdjuːsər/
A device that changes energy from one form to another, like converting sound into electrical signals or light into electrical signals.
The engineer used a transducer to convert the sound waves into electrical signals for analysis.
Transducer → It is formed from "trans-" (meaning across) and "ducere" (meaning to lead). The word describes a device that leads or converts energy from one form to another across a medium.
Think of a device that 'leads' ('ducere') energy 'across' ('trans-') different forms, which is what a transducer does.
