There are various electrical and electronic components are used to build the circuits and projects for engineering students. In general, the process of transduction involves the conversion of one form of energy into another form. This process mainly includes a sensing element to sense the input energy and then converting it into another form by a transduction element. Measurand tells the property, quantity, or state that the transducer looks to translate into an electrical output. A transducer is an electrical device that is used to convert one form of energy into another form.
