Which statement best defines voltage in electrical circuits?

• A. The force that pushes electrons through a conductor
• B. The rate of doing work
• C. The amount of charge in a conductor
• D. The flow of electric charge

Answer: (A)

Voltage is the force that pushes electrons through a conductor because it represents the electric potential difference that drives charge movement. Think of it like pressure in a water hose: the greater the pressure, the more force there is to push water through the nozzle, just as a higher voltage pushes charges through a circuit. This pushing action is what causes current to flow when a complete path exists, and it reflects the energy per unit charge available to move electrons.

Voltage is not the rate of doing work—that’s power. It’s not the amount of charge in a conductor—that would be the total charge. It’s not the flow of electric charge—that’s current. So the statement that voltage is the force that pushes electrons through a conductor best captures what voltage does in a circuit.
