Most practical applications of electricity
Correct answer: C. Charge in motion
- A. Molecules in motion
- B. Electrons at rest
- C. Charge in motion
- D. Atoms in notion
Explanation
"charges in motion," emphasizes the significance of electric charges, typically electrons, flowing through conductive materials. This motion of charges is fundamental in practical applications of electricity, powering devices and systems in electrical circuits.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
