An electric cell is a single unit of a battery, often found in dry-cell formats like AA or AAA, while an electric circuit is a collection of components that work together to perform a function. In automotive batteries, multiple cells combine to create a higher voltage, with each cap representing a 2V cell in a 12V battery. The distinction lies in the fact that a cell generates electrical energy, whereas a circuit facilitates the flow and use of that energy. Understanding these differences is crucial for grasping basic electrical concepts. The discussion clarifies the fundamental roles of cells and circuits in electrical systems.
