Question #26733
a certain conductor has a resistance of 10 ohms at 20 degree C and increased to 11.35 ohms at a certain temperature. if temperature coefficient based on 20 degree C is 40 x 10 E -4 / C degree, find the final temperature
Expert's answer
a certain conductor has a resistance of 10 ohms at 20 degree C and increased
to 11.35 ohms at a certain temperature. if temperature coefficient based on
20 degree C is 40 x 10 E -4 / C degree, find the final temperature
As the resistance difference of a conductor is
& Delta;R = 11.35[Ω] - 10[Ω] = 1.35[Ω]
the temperature difference is
& Delta;t = 1.35[Ω] / 0.0040 [Ω/°C] = 337.5[°C].
Therefore, the final temperature of a conductor is
T = 20[°C] + 337.5[°C] = 357.5[°C].
