which of the following characteristics of electrons determines the current in a conductor?
1. drift velocity alone
2. thermal velocity alone
3. both drift velocity and thermal velocity
4. neither drift nor thermal velocity

Correct option is: (1)
The characteristic of an electron that determines the current in a conductor is drift velocity alone and not thermal velocity.
Drift velocity is the average velocity with which the free electrons get drifted towards the positive end of the conductor under the influence of an external electric field.
On the other hand thermal velocity of electron depends upon the temperature.

- drift velocity is directly proportional to
- What is resistance?
- If the temperature of a conductor decreases,how does the relaxation time of electrons in the conductor change?
- explain slow electrons and fast electricity concept.. why electricy travel fast whereas the electron in it have very low velocity.
- How does a metal conduct electricity?
- Obtain the relation between the terms drift velocity, relaxation time and electric field
- Current flows from a point that has higher electrical potential to a point of lower electrical potential potential ,didn't understand
- DRIFT VELOCITY
- Define drift velocity of electrons for a metallic conductor.
- Large amount of current can be obtained from the small drift velocity and small electronic charge in a conductor. Why?
