Which term best defines the energy of moving electrons?

• A. Electrical Energy
• B. Chemical Energy
• C. Thermal Energy
• D. Nuclear Energy

Answer: (A)

Electrical energy is the energy associated with the movement of electric charges. When electrons drift through a conductor under a potential difference, they carry energy that can be delivered to devices and transformed into light, sound, or heat. This energy comes from the work a power source does to move charges against resistance. It’s different from chemical energy (stored in bonds), thermal energy (random molecular motion), and nuclear energy (from forces inside the nucleus). In circuits, the rate of transferring that energy is power (P = IV), and over time it can do useful work.
