Let's write the relationship between the electrical potential difference, potential energy and the amount of charge:


ΔV=Wq=ΔPEq,\Delta V=\dfrac{W}{q}=\dfrac{\Delta PE}{q},q=ΔPEΔV=6 J12 V=0.5 C.q=\dfrac{\Delta PE}{\Delta V}=\dfrac{6\ J}{12\ V}=0.5\ C.

Answer:

A 12-volt battery will increase the potential energy of 0.5 coulombs of charge by 6 joules.
