Question

Point A is at a lower electrical potential than point B. An electron between them on the line joining them will

• A. move towards A
• B. move towards B
• C. move at right angles to the line joining A and B
• D. remain at rest

Answer 1

The correct option is B move towards B

Given that point $A$ is at lower electric potential than point $B$. The electron between them on line joining will move.

We have to find where this electron moves.

Since we know that electric currents move from a higher potential or a lower potential. Also, electrons move in the direction opposite to electric current. So the electron on the line joining two points $A$ and $B$ will move from lower to higher potential i.e, it will move towards $B$.
