A. Identify whether each statement is true or false. 1. 2. 3. 4. 5. The electric potential Vab of Va with respect to V₂ is equivalent to the work done by the force when a charge moves from one point to another. One V is equivalent to one coulomb per joule. Electric potential and electric potential energy are similar terms. The SI unit of electric potential is 1 volt (V). As the positive charge transfers through the external circuit from the negative to the positive terminal, electric potential energy and the corresponding potential increase.
