A charge of #8 C# is passing through points A and B on a circuit. If the charge's electric potential changes from #36 J# to #6 J#, what is the voltage between points A and B? Physics Electrical Energy and Current Electric Potential 2 Answers Jane Feb 25, 2018 Voltage difference = the change in potential energy/charge So, we can say as potential energy of charge at #A# is higher than that at #B# , #A# is at higher voltage than #B#, So,the Voltage difference between them is #(36-6)/8 =3.75 V# James W. Feb 25, 2018 Answer: The voltage between A and B is 4V (1s.f.) Explanation: The change in energy is #30J# and the charge is #8C# Using the formula #E=QV#, since voltage is simply the energy gained/lost per coulomb of charge, #V= 30/8 = 3.75V# Related questions Why does electric potential increase with distance?
