Question

define temperature coefficient of resistivity obtain an expression for it?​

Answer 1

Answer:

The temperature coefficient of resistance is defined as the Change in resistance per unit resistance per degree rise in temperature based upon the resistance of 0∘C. R(T)=R0(1+∝ΔT) ….( 1) Where, R (T) =Resistance at any temperature. R0= resistance at temperature 0∘
