Copper temp coefficient of resistance
WebAnswer (1 of 3): Assuming you actually mean thermal resistance, rather than electrical resistance, the answer would be non trivial because wire is cylindrical. Thermal … WebApr 13, 2024 · 12. Repeat the experiment for different temperature t1, t2….and note corresponding resistance X1, X2... Temperature coefficient of resistance is found using equation A=(X2-X1)/(X1t2-X2t1) Repeat the experiment for unknown resistance 2. A graph is plotted between values of X and t , which gives a straight line, whose slope is α. 13.
