A charge of #8 C# is passing through points A and B on a circuit. If the charge's electric potential changes from #27 J# to #3 J#, what is the voltage between points A and B? Physics Electrical Energy and Current Electric Potential 1 Answer Narad T. Aug 25, 2017 The voltage is #=3V# Explanation: The charge is #Q=It# We apply Ohm's Law #U=RI# The power is #P=UI# And the energy is #E=UIt# #E=UQ# and #DeltaE=QDeltaU# The voltage is #DeltaU=(DeltaE)/Q=(27-3)/8=3V# Answer link Related questions Why does electric potential increase with distance?
