In the Resistive Transducer principle, the resistance of a resi... | Filo

An elastic resistive transducer with an initial resistance, Ro, and length, lo, is stretched to a new length. Assuming that the cross-sectional area of the transducer changes during stretching, derive a mathematical relationship for the change in resistance DR as a function of the initial length, lo; the change in length, Dl; the volume of the transducer, V; and the resistivity, r. | Numerade
