Which of the follwing characteristies of electrons determines the current in a conductor?

Options

A. Drift velocity alone
B. Thermal velocity alone
C. Both drift velocity and thermal velocity
D. neither drift nor thermal velocity

Answer

A

Explanation

The relationship between current and drift velocity is given by-
`I = "ne"Av_(d)`
Here, I is the current and `v_(d)` is the drift velocity. So, `I prop v_(d)`
Thus, only drift velocity determines the current in a conductor.
