What is the relationship defined by Ohm's Law?

• A. The product of voltage and current equals power
• B. The product of resistance and current equals voltage
• C. Voltage equals the product of current and resistance
• D. The product of resistance and voltage equals current

Answer: (C)

Ohm's Law describes the relationship between voltage, current, and resistance in an electrical circuit. The law states that voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with the resistance (R) being the proportionality constant. Mathematically, this is represented as V = I * R. In this context, the correct choice accurately represents the relationship defined by Ohm's Law, where voltage equals the product of current and resistance. This fundamental principle is crucial for analyzing and designing electrical circuits, as it allows engineers to calculate one of the three variables (voltage, current, or resistance) if the other two are known. Understanding this relationship is essential for effective troubleshooting and implementation of electrical systems.
