What energy flows through wires from a power plant to outlets?

• A. Electrical Energy
• B. Light Energy
• C. Sound Energy
• D. Chemical Energy

Answer: (A)

Electrical energy is the energy that flows through wires from a power plant to outlets. Power plants convert other forms of energy—like chemical energy in fuels or nuclear energy—into electrical energy, which travels through conductors as an electric current and an accompanying electromagnetic field. This is the form of energy that devices use when plugged in, and they then convert it into light, sound, motion, or heat as needed. Light energy is carried by photons and travels through space or lenses, not primarily along electrical wires. Sound energy moves as vibrating matter in a medium, not through wires. Chemical energy is stored in bonds within molecules; it’s the initial source that a plant converts to electricity, but the energy flowing through the wires at that moment is electrical energy.
