Concept explainers

Resistivity

Resistivity is a characteristic property of the conductor’s material that measures the extent to which the material opposes the flow of current. It is denoted by the Greek letter “rho”. Electrical resistivity, also known as specific resistance, depends on the nature of the material of the conductor and is unaffected by its dimensions.

Question

(b) If the resistor is made of carbon, what will its resistance be when its temperature is increased by 68.0 C°? (The temperature coefficient of resistivity for carbon is −5.0 10^-4 (°C)^-1.) Amp=1.33
