| Abstract: | An inexpensive, indigenous and a simple electronic instrument based on voltage follower, currentto-voltage converter, zero crossing detector and a phase detector has been developed for measurement of a.c. conductivity. Real and imaginary parts of complex impedance are determined for a given sample as a function of frequency and the given sample is represented by a pure electronic model. |
