What is Ohm’s Law?

Ohm's Law is fundamentally a principle that illustrates how voltage, current, and resistance are interrelated in an electrical circuit, specifically stating that Voltage (V) equals Current (I) multiplied by Resistance (R). This relationship is crucial for understanding how electrical circuits function.

When applying Ohm's Law, it becomes clear how manipulating one of the variables—voltage, current, or resistance—affects the others. For instance, if the resistance in a circuit is constant and the voltage increases, the current will also increase proportionally. This formula is essential for electrical engineering and practical applications in circuit design and troubleshooting.

While other answer choices present related concepts or aspects of electrical engineering, they do not accurately define Ohm’s Law. The first option discusses the relationship between voltage, current, and power, which is relevant but not specific to Ohm's Law. The third option focuses on measuring electrical resistance, which is an aspect of circuit behavior but does not encapsulate the law itself. The fourth option talks about the flow of electrons, which is a description of current but, again, not a definition of Ohm's Law.
