Question

the resistance of a fixed coil measures 55 ohms at 25 degrees Celsius and 65 ohms at 75 degrees Celsius find the temperature coefficient of the conductor at zero degree celsius​

Answer 1

To change degrees Celsius in degrees Fahrenheit, the formula is:

F = 1.8C +32F=1.8C+32

So,C = 1.8C +32C=1.8C+32

C = -40C=−40

T=-40+273.15=233.15\ KT=−40+273.15=233.15 K
