Answer:
An electron has a high potential energy when it is at a location associated with a more negative value of potential, and a low potential energy when at a location associated with a more positive potential.
The reason is that electrical charge has two types: positive and negative which exert attractive forces on each other but repulsive forces on themselves. A more positive potential is produced by an accumulation of positive charge (which attracts negatively charged electrons) and a more negative potential is produced by an accumulation of negative charge (which repels electrons).
