What term describes a device that provides electrical energy and can consist of multiple cells?

• A. Buzzer
• B. Capacitor
• C. Cell
• D. Battery

Answer: (D)

Think about what each term represents in terms of energy sources. A cell is the basic energy-producing unit that generates a small voltage. When you connect multiple cells together, you create a device that can supply a higher voltage or greater capacity; that assembled unit is called a battery. A capacitor stores energy temporarily and releases it in bursts, not as a steady chemical energy source. A buzzer uses electrical energy to produce sound rather than serving as the energy source itself. So, the term for a device that provides electrical energy and can consist of multiple cells is battery.
