Effect of temperature on Resistance
__________________________________________________________________________________ __________________________________________________________________________________ We know that there are some materials whose resistance remains same and they offer same resistance for the flow of current despite of increasing the applied voltage. Those materials whose resistance remains same and provide same resistance for the flow of current and the flow of current increases with the increase in applied voltage are called Ohmic materials. Some examples of such materials are Copper, Silver, Nichrome, Manganin, Constantan etc. But for some materials including conductors and insulators, the resistance does not remains same by positive or negative change in temperature and in this article, we will explain and exemplify such materials. 1. Effect of temperature on conductors: Conductors are those materials which have the availability of free e...
