There is a 12 V potential difference between the positive and negative ends of the jumper cables, which are a short distance apart. An electron at the negative end ready to jump to the positive end has a certain amount of potential energy. On what quantities does this electrical potential energy depend

1. Potential difference

2. Charge

Explanation:

There exists a potential difference between charges because each coulomb of charge has a different potential energy at the end of jumper cables.

V = E/Q

or

E = VQ

As you can see in the above equation the energy is directly proportional to potential difference and the amount of charge.

Therefore, we can conclude that electric potential energy depend on potential difference and charge.
