ABSTRACT
This paper states the application of a ferroelectric substances in measurement of current using the property that their dielectric constant increases with temperature. Since the change in dielectric constant with temperature is very steep, the resolution of the current measuring device will be very high. Binary and ternary oxides have been used based on perovskite systems. The compounds have been synthesised, characterised with respect to their crystal structure and their dielectric constants have been measured
