As a good first approximation
As a good first approximation when looking at the conductionelectrons we may consider the metal to be at ? = 0 even though theactual temperature is 300 ?. Explain why this is a validapproximation.
Answer:
When there is no electric field applied even then the electronshave a velocity due to their thermal energy.But on a an everageeventhough the electrons move the net current flowing through agiven crossection is zero.
