How much work does an ideal battery with a 7.70 V do to an electron that passes through the battery from the positive to the negative terminal?

W = 7.7 eV

Explanation:

We need to find the work done by an ideal battery with a 7.70 V to an electron that passes through the battery from the positive to the negative terminal.

Let W is the work done. Work done by moving a charge is given by the formula as follows :

W = qV

Here, q = e

W = eV

W = 7.7 eV

So, the required work done is 7.7 eV.

this is a good question! i'll do some research and come back when i have the answer!
