_____ is the force that pushes electrons through a conductor.

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

Answer: (D)

Voltage is the force that pushes electrons through a conductor. It represents the electric potential difference between two points, creating an electric field inside the material. The electrons feel a force from this field and start to drift, producing current. How much current flows depends on the conductor’s resistance, described by I = V/R. Capacitance is about storing charge, not driving current, and resistance is the opposition to the flow. So the push behind electron movement is voltage.
