Voltage is sometimes referred to as what because it is like pressure?

• A. Electric force
• B. Electrical momentum
• C. Magnetic flux
• D. Electric pressure

Answer: (D)

Voltage acts like the pressure that pushes charges to move through a circuit. It’s the difference in electric potential between two points that provides the driving “push” for current when a path exists. This isn’t a force itself on a charge; the actual force on a charge is given by F = qE, but voltage tells us how much energy per unit charge is available to drive that motion, much like how pressure differences drive fluid through pipes. Calling it electric pressure captures that intuitive idea of a push that makes current flow. The other terms refer to actual forces, momentum, or magnetic effects, which aren’t what voltage represents.
