Passive Transducer

Detailed explanation-1: -Transducers which require an external power source for their operation is called a passive transducer. They produce an output signal in the form of some variation in resistance, capacitance, or any other electrical parameter, which then has to be converted to an equivalent current or voltage signal.
Detailed explanation-2: -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.
Detailed explanation-3: -Passive transducers, on the other hand, need an external power source to operate. Their output signal is produced in the form of variation in resistance, capacitance, or other electrical parameters.
Detailed explanation-4: -A passive transducer is said to be a capacitive transducer, when it produces the variation (change) in capacitance value.
