What are volts according to the material?

• A. The unit of electrical resistance.
• B. A measure of current flow through a conductor.
• C. A measure of electrical power usage.
• D. The amount of pressure coming out of an electrical source.

Answer: (D)

Volts represent the electrical potential difference—the pushing force that drives current through a circuit. It’s like water pressure in a pipe: when there’s more pressure, more charge is pushed to flow through the conductor. That pushing force is what volts quantify, coming from the electrical source. This isn’t about resistance, current, or power themselves—those have their own units (ohms, amperes, watts). Grasping voltage as the driving pressure helps you predict how much current will move when a path exists, as described by V = I × R.
