What is electricity commonly defined as?

• A. The flow of electrons
• B. The accumulation of charge on an object
• C. The rotation of charges
• D. The transfer of energy in a circuit

Answer: (A)

Electricity is the flow of electric charge. In metal wires this means electrons moving through the material, which creates an electric current—the rate at which charge passes a point. If charges just accumulate and stay on an object, that’s static electricity, not a current. The idea of charges "rotating" isn’t how electricity is described in physics. The transfer of energy in a circuit describes what electricity can do (deliver power) but isn’t the definition of electricity itself. So the best definition is the flow of electric charge, usually electrons in a conductor.
