What term is defined as electrical potential, electrical pressure?

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

Answer: (A)

Voltage is electrical potential, or electrical pressure—the push that makes charges move through a circuit. It’s the potential difference between two points that drives current when a path exists. Measured in volts, voltage determines how strongly the source can push current; the higher the voltage, the greater the driving force for current, as described by Ohm’s law (I = V/R). The other terms describe what happens to that push: current is the actual flow of charges, resistance is the opposition to that flow, and grounding is a safety path to earth.
