Battery is a source of current; the current leaving the battery is always same B

Question

Battery is a source of current; the current leaving the battery is always same Battery supplies energy to circuit Battery has a potential difference equal to its emf. A region of space contains a uniform electric field, directed toward the right, as shown in the figure. Which statement about this situation is correct? The potential at all three locations is the same. The potentials at points A and B are equal, and the potential at point C is higher than the potential at point A. The potential at points A and B are equal, and the potential at point C is lower than the potential at point A. The potential at point A is the highest, the potential at point B is the second highest, and the potential at point C is the lowest.

Explanation / Answer

the positive charges go towards lower potential, in the same direction as electric fields.

when a positive charges drop anywhere in the diagram, they will move to the right, so the potential is lower to the right.

the charges won't move up or down. This means that the potential doesn't change when you move up or down.

then, The potential at points A and B are equal (they are moving up or down), and the potential at point C is lower than the potential at point A. (it move to the right)
