What term describes the push that causes electrical charge to move in a circuit?

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

Answer: (A)

Voltage difference, or electric potential difference, is the driving push that makes charges move in a circuit. It’s like the pressure that pushes water through a hose—the greater the voltage difference between two points, the stronger the push on charges, and the more current can flow (assuming resistance stays the same). The current is the actual flow of charges, resistance is how much the circuit opposes that flow, and power is the rate at which energy is transferred, given by P = V × I. So the term describing the push is voltage difference.
