Which energy type is associated with the flow of electrons in circuits?

• A. Mechanical
• B. Nuclear
• C. Electrical
• D. Radiant

Answer: (C)

Electrical energy is the energy tied to the flow of electric charges in circuits. When a voltage source pushes electrons through wires, the moving charges carry energy that can be transformed by devices like lamps, motors, or resistors. The rate of energy transfer is power, which depends on voltage and current. Mechanical energy relates to moving or stored energy of objects, nuclear energy comes from processes in atomic nuclei, and radiant energy is carried by light and other electromagnetic waves. Since circuits involve the movement of electrons delivering energy to components, electrical energy best fits the situation.
