What is the resistance of the coil A at 600 kelvin if its resistance at 300 kelvin is 50 ohms? (Assume the temperature coefficient of resistance of the coil is .007/ degrees C)

Answer 1

C = K-273.2 = 600 - 273.2 = 326.8Deg.

C = 300 - 273.2 = 26.8Deg.

R = Ro + a*Ro(T-To).
R=50 + 0.007*50(326.8-26.8) = 155 Ohms
