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?
