Question

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

Answer 1

Answer:

Explanation:

The electric potential energy of the electron depends on the potential difference applied between the two ends of the cable. Indeed, the electric potential energy of a charge is given by

$U=q \Delta V$

where q is the magnitude of the charge,

Δ v is the potential difference applied

So, U depends on Δ v

Answer 2

Answer:

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.
