Which law is most closely related to the measurement of voltage in relation to current and resistance?

• A. Faraday's Law
• B. Ohm's Law
• C. Newton's Law
• D. Kirchhoff's Law

Answer: (B)

The connection between voltage, current, and resistance is fundamentally described by Ohm's Law. This law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. In a mathematical form, it can be expressed as V = I × R, where V represents voltage, I represents current, and R represents resistance. Ohm's Law is essential in understanding how electrical circuits function and allows technologists to analyze and predict the behavior of electrical components under different conditions. By applying this law, technologists can effectively troubleshoot and ensure the equipment's functionality. On the other hand, Faraday's Law concerns electromagnetic induction and the relationship between electric fields and magnetic fields. Newton's Laws pertain to motion and forces, not electrical properties. Kirchhoff's Laws are important for analyzing complex circuits, specifically about the conservation of charge and energy, but they rely on an understanding of Ohm's Law for their application. Thus, Ohm's Law is the most appropriate choice for the question regarding the measurement of voltage in relation to current and resistance.
