The measure of energy between any two points on a circuit is:
Correct answer: E. Potentíal difference
- A. Resistance
- B. Electromotive force
- C. Internal resistance
- D. Resistivity
- E. Potentíal difference
Explanation
Potential difference, often referred to as voltage, is the difference in electric potential between two points in an electric field. It represents the work done per unit charge to move a charge between those two points.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
