Why does an electron move in the direction opposite to the electric field?

wer: A. The direction of electric fields is based on positive charges. This means the electric field lines will point from the positive change to the negative charge. Since opposite changes repel, if you were to put an electron inside the field, it would accelerate to the positive change, or in the opposite direction of the electric field.
