Positive temperature coefficient of resistivity (PTCR) is the most important and interesting phenomena shown by CPC, where the resistivity of the CPC increases at certain temperature (PTC trip), making the composites electrically insulating one.
This effect is known as positive temperature coefficient of resistivity (PTCR) (10-12), PTCR is generally followed by a decrease in the resistivity with further increase in temperature and is termed as negative temperature coefficient of resistivity (NTCR) effect (13-15).
