Answer:
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.
