Which of the following characteristics of electrons determines the current in a conductor? a) drift velocity alone b) thermal velocity alone c) both drift velocity and thermal velocity d) neither drift nor thermal velocity
Correct option is A) A. Drift velocity only. The current in a conductor, I=neAVd where, n= no. of free charge density A= cross-sectional area of conductor Vd= Drift velocity From the above, Drift velocity is only responsible for the current in a conductor
