What is Ohm's Law?

• A. Current equals voltage times resistance
• B. Current is directly proportional to resistance
• C. Current is inversely proportional to resistance
• D. Voltage equals current divided by resistance

Answer: (C)

Ohm's Law is a fundamental principle in electrical engineering that describes the relationship between voltage, current, and resistance in an electrical circuit. The correct statement of Ohm's Law is that voltage (V) is equal to the current (I) multiplied by the resistance (R). This mathematically can be expressed as V = I * R. In this context, option C, which asserts that current is inversely proportional to resistance, does not accurately describe the relationship established by Ohm's Law. Rather, Ohm's Law implies that as resistance increases, for a given voltage, the current actually decreases, which aligns with the correct understanding of electrical relationships but does not state that they are inversely proportional in the general sense presented in this choice. Understanding that Ohm's Law describes how current varies directly with voltage and inversely with resistance helps clarify the nature of the relationship among these electrical parameters. The correct representation identifies how the increase or decrease of one element directly affects others in the circuit.
