Active transducer is a device which converts the given non-electrical energy into electrical energy by itself. What are the Passive / Active Voice Differences? It is kind of transducer whose interior parameters including capacitance, resistance and inductance modifies or changes when it comes in contact with any passive element. Active and passive devices provide different outputs. The major difference between active and passive transducer is that an active transducer has the ability to convert one form of energy into another form (electrical) without using an external source of power. Therefore they are also called as self generating type transducers. Active Transducers. An example of a non-electrical conversion, in which a physical element is converted into another physical element, is a simple mercury-filled thermometer. Difference Between Active & Passive Transducer The most crucial difference between the active and passive transducer is that the active transducer does not use any external power source for producing the output, whereas the passive transducer requires the additional energy source for working. Most transducers, however, involve electricity to perform a variety of very useful tasks. Some of the most commonly electrical quantities in a transducer are resistance, capacitance, voltage, current or inductance. • R, C, I component and its effects.
