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? view available hint(s)

Answer 1

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, while
`\Delta V` is the potential difference applied. So, U depends on
`\Delta V`.
