What is the force with which electrons travel?

• A. Resistance
• B. Voltage
• C. Current
• D. Power

Answer: (B)

The force that pushes electrons to move through a conductor is provided by voltage, the electric potential difference created by a source like a battery. This voltage sets up an electric field inside the wire, and that field exerts a force on the charged electrons, driving them to flow. The stronger the voltage, the stronger the push, and thus more current flows for the same resistance (I = V/R). Resistance is what opposes that motion, current is the actual flow of electrons, and power is how quickly energy is transferred—not the driving force itself.
