Current and Drift Velocity (multiple choice)

[SOLVED] Current and Drift Velocity (multiple choice)

1. In a dental X-ray machine, the movement of accelerated electrons is east. The current associated with these electrons is in what direction: (a) east, (b) west, or (c) zero?









3. At first I thought it was B (west) because as the electrons(-ve charge) are moving east, it is equivalent to a +ve charge moving west, conventional current towards west. But then it seems as if the answer could be C (zero). Which answer is correct?

Accelerated electrons always constitute a current provided that majority of the acceleration contributes to the same direction, which in your case is east.

and yes.. the current is going west as u said..
