1 Answer

Answer :

1. Active Transducer: -

• These transducers do not need any external source of power for their operation. Therefore, they are also called as self-generating type transducers.

• The active transducer are self-generating devices which operate under the energy conversion principle.

2. Passive Transducer: - 

• These transducers need external source of power for their operation. So they are not self-generating type transducers.
