*Corresponding author: Mohd Hamzah Harun ([email protected]) ABSTRACT: The alternate current (ac) electrical conductivity of poly(vinyl alcohol)polypyrrole-ferric chloride (PVA-PPy-FeCl3) composite films has been investigated at different temperatures at a frequency ranging from 20 Hz to 1 MHz. The electrical conductivity of the composite increased with increasing temperature and it obeys power law Aωs in which s in the range 0.3
