Problem: What is the resistance of a carbon rod at 25.8 degrees C if its resistance is 0.0160 ohms at 0.0 degrees C?

FREE Expert Solution

The variation of resistance with temperature is expressed as:

R=R0[1+α(T-T0)], where R is the resistance of the material at a temperature, T degrees Celcius, R0 is the resistance of the material at T0 degrees Celcius, and α is the temperature coefficient of a material. 

T is the final temperature and T0 is the initial temperature.
