Relation between Resistance and Heat/Temperature
Asked by RACHIT_MAHAAN | 23rd Dec, 2009, 07:47: PM
As the temperature of the resistor increases, i.e. heat, the electron get more energetic and hence frequently collide with atoms and with each other, and hence resistance increases.
So resistance is directly propotional to the temperature.
While using the above formula, please note that while the temperature increases, and resistnace increases, the current or potential difference can't be always constant. Hence merely rearranging the formula won't help.
