Which term describes the total amount of electrical energy that a source can deliver over time, including ampere-hours?

• A. Capacity
• B. Ampere
• C. Ammeter
• D. Carbon pile

Answer: (A)

Capacity is the term that describes how much electrical energy a source can deliver over time, including ampere-hours. It represents the total charge available, often measured in ampere-hours (Ah), which tells you how long the source can supply a given current before depleting. Ampere is a unit of current (a rate at a moment), so it doesn’t capture total energy over time. An ammeter is simply the instrument used to measure that current, and a carbon pile is a device used to load a source during testing. So capacity best fits the idea of total energy deliverable over time, incorporating ampere-hours. For reference, the energy content is voltage times ampere-hours (Wh), but the descriptor for total deliverable charge over time is capacity.
