The electric potential difference between points A and B, \(V_B - V_A\) is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta .

You can measure current and potential difference in circuits. They are different things and so are measured in different ways. Current is a measure of how much electric charge flows through a...
Figure 7.3.5.3: A typical electron gun accelerates electrons using a potential difference between two metal plates. The energy of the electron in electron volts is numerically the same as the voltage between the plates. For example, a 5000 V potential difference produces 5000 eV electrons. Definition: ELECTRON VOLT.
The electric potential difference or voltage of a battery is the potential energy difference across its terminals for every Coulomb of charge. A high voltage battery maximizes this ratio of energy/charge by doing a lot of work on each charge it encounters.
Develop a qualitative understanding of potential difference, current and resistance before combining them mathematically. Use the equation as a shorthand for an already understood relationship between them.
You can measure or predict both current and potential difference. Combine these two measures to calculate which circuit components will shift this energy. One part of the loop where we do not want energy shifted is the wires.
Describe the relationship between potential difference and electrical potential energy. Explain electron volt and its usage in submicroscopic process. Determine electric potential energy given potential difference and amount of charge.
