What is the force that moves electrons through a circuit called?

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

Answer: (B)

The force that moves electrons through a circuit is the electric potential difference, or voltage. It acts like pressure that creates an electric field, pushing charges to move whenever a complete path exists. The actual flow of electrons—the current—is what results from that push and is governed by both the voltage and the circuit’s resistance (I = V/R). Resistance opposes the flow, so for the same voltage, higher resistance means less current. Power describes how quickly electrical energy is delivered (P = V I). In short, voltage is the driving force behind the movement of electrons.
