Which statement correctly describes a battery?

Which statement correctly describes a battery?

• A. A device that measures resistance
• B. Made up of two or more cells connected together
• C. A circuit symbol for resistor
• D. A wiring symbol

Answer: (B)

A battery stores chemical energy and converts it to electrical energy. A single cell is the basic unit, but a battery is formed by two or more cells connected together, which lets it provide higher voltage or greater capacity. That makes the description of a battery as being made up of multiple cells connected together the correct choice. The other statements describe different things: measuring resistance is what an ohmmeter does, the circuit symbol for a resistor is a specific schematic symbol, and a wiring symbol refers to how components or connections are drawn in diagrams.
