Which term describes electrical potential, the pressure that pushes charges through a circuit?

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

Answer: (A)

Voltage describes electrical potential, the pressure that pushes charges through a circuit. Think of it like water pressure in a hose—the higher the pressure, the more it pushes water along. In circuits, voltage is the driving force that moves charges from one point to another. The actual flow of charge, or current, depends on this pushing force and the resistance in the path (I ≈ V / R). Grounding is just a reference point with zero volts and a safe return path, not the push itself. So voltage is the term that matches the description.
