Question

Which of the following characteristics of electrons determinants the current in a conductor?

• A. Draft velocity alone
• B. Therminal velocity alone
• C. Both draft velocity and thermal velocity
• D. Neither draft nor thermal velocity

Answer 1

Answer: (A)

Draft velocity alone

Answer 2

: Current in conductor I = ne A vd

Hence current in a conductor is determined by drift velocity and does not depend upon thermal velocity.
