The question here has been framed wrongly. There is nothing like a general circuit for a transducer. Depending on a transducer you may have many circuits. For eg. a Piezoelectric crystal is a transducer, it can convert both ways; mechanical vibrations to electrical and electrical to mechanical. So you see, there is nothing like a general circuit for a transducer.
Another better example would include an Antenna which converts electro-magnetic waves into a electric signal.
All that you can say at max is that a transducer is a device that converts one form of energy to another. And that is either due to the virtue of the property of a material or due to a certain circuitry which will vary from transducer to transducer.
what is the electrical circuit arrangement for the reflective opto transducer
The basic principle of a transducer: A transducer which converts a physical quantity to the electrical quantity.
basically an input is given to the transducer, which is the 1st basic block of instrumentation system. this transducer's o/p goes to the signal conditioning circuit whose o/p is then given to the recorder, analog meter, digital transistor, printer, controller, oscilloscope and the punch card.
its a thing that you use to build a circuit....

what type of transducer potentiometer
There is no direct sound-light transducer but you could connect a microphone and amplifier to a suitable l.e.d. driving circuit.
