1.	If the temperature of a metal is increased ,the temperature coefficient of the residence.
Answer» When temperatures rise, metals experience a small increase in length, width, overall area, and volume — a phenomenon known as thermal expansion. Thermal expansion occurs due to an increase in atomic vibrations with the magnitude of the expansion depending on the specific metal. We know that, R = R₀ [1 + \(\alpha\) (T - T₀)] where, R = conductor resistance at temperature T R = conductor resistance at reference temperature T. \(\alpha\) = temperature cofficient of resistance for conductor material. The resistance change per degree of temperature change. as all materials have a certain specific resistance (at 20°C) , they also change resistance according to temperature by certain amounts. For pure metals, this cofficient is a positive number, meaning that resistance increase with increasing temperature.
