Draw a graph showing variation of resistivity with temperature of nichrome. Which property of nichrome is used to make standard resistance coils ?

Text Solution

Verified by Experts

At low temperature (or zero) the resistivity increase as a higher poer of temperature. Then linearly increase with increase in temperature.
