CUET Preparation Today
| Which of the following characteristics of electrons determines the current in a conductor? |
Only Drift velocity Only thermal velocity Both drift velocity and thermal velocity. Neither drift nor thermal velocity. |
| Only Drift velocity |
| 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. |
