Concept explainers

Temperature Variance of Resistance

Electrical resistance or simply resistance is the property of a material that opposes the free flow of electrons through it. The total amount of resistance to the flow of charges (or current) is affected by many factors like the length of the conducting material, its cross-sectional area, resistivity, and temperature.

Question

A metal wire has a resistance of 10.00 A at a temperature of 20.0°C. If the same wire has a
resistance of 10.55 l at 90.0°C, what is the resistance of this same wire when its
temperature is 220°C? *
