A superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance.This means no heat, sound or any other form of energy would be released from the material when it has reached critical temperature (T. superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance.
Transducers: Devices used to transform one kind of energy to another. When a transducer converts a measurable quantity (sound pressure level, optical intensity, magnetic field, etc) to an electrical voltage or an electrical current we call it a sensor. We will see a few examples of sensors shortly. When the transducer converts an electrical signal into another form of energy, such as sound (which, incidentally, is a pressure field), light, mechanical movement, it is called an actuator. Actuators are important in instrumentation. They allow the use of feedback at the source of the measurement.
