The force that causes electric charge to flow is called?

Voltage is the driving force in an electrical circuit. It’s the electric potential difference between two points that pushes free charges to move through a conductor. Think of it like water pressure: higher pressure pushes more water through a hose. In a circuit, a power source establishes this potential difference, and the stronger the push (higher voltage), the more current will flow for a given resistance. Current is the actual flow of charges, resistance is what opposes that flow, and capacitance relates to storing charge and influencing how current changes over time. So the force that drives the flow is voltage.
