What does Ohm's Law primarily measure?

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

Answer: (D)

Ohm's Law primarily measures the relationship between voltage, current, and resistance in an electrical circuit. It is a fundamental principle in the field of electronics and electrical engineering. The law is often expressed in the formula V = IR, where V represents voltage, I represents current, and R represents resistance. This demonstrates that resistance is the factor that determines how much current will flow through a conductor for a given voltage. By understanding Ohm's Law, one can analyze how changes in voltage or resistance affect current flow. This makes resistance a key concept in various applications, such as designing circuits and calculating safety limits in electrical systems. Thus, Ohm's Law provides critical insights into the nature of electrical circuits and is foundational to the analysis and understanding of electrical components and their interactions.
