Ohm's Law refers to which three electrical terms?

• A. Amperage, voltage, and resistance
• B. Power, voltage, and resistance
• C. Current, power, and capacitance
• D. Resistance, inductance, and impedance

Answer: (A)

Ohm's Law describes how voltage, current, and resistance relate in a circuit. It can be written as I = V / R, meaning the current (amperage) depends on the voltage across two points and the resistance between them. Amperage is simply another word for current, so the three terms involved are voltage, current (amperage), and resistance. That makes the option listing amperage, voltage, and resistance the best fit because it names exactly the quantities linked by Ohm's Law.

The other options introduce concepts not part of the basic V–I–R relationship: power is related to voltage and current through P = V × I but isn’t one of the three quantities in the fundamental equation; capacitance and inductance describe energy storage and reactive behavior, not the simple DC relation; impedance combines resistance with reactance in AC circuits.
