What is the electrical term for the force that causes electron flow?

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

Answer: (B)

The correct answer is voltage, which is defined as the electrical potential difference between two points. It is the force that pushes electrons through a circuit, allowing them to flow. Voltage can be thought of as the "pressure" in an electrical system that drives the current, similar to how water pressure encourages water to flow through a pipe. In a circuit, when there is a difference in voltage across components, this difference creates an electric field that compels electrons to move, which results in an electric current. Understanding voltage is crucial for grasping how electrical systems work, as it essentially initiates and sustains the flow of electrons essential for powering devices. The other terms relate to various aspects of electrical behavior. Current refers to the actual flow of electrons in a circuit, while power is the rate at which electrical energy is transferred. Resistance is a measure of how much a component opposes the flow of current. While all these concepts are interrelated, voltage specifically describes the force that drives electron flow.
