In the context of electrical circuits, what does Ohm's Law fundamentally relate?

• A. Voltage, power, and capacitance
• B. Voltage, current, and resistance
• C. Power, current, and resistance
• D. Voltage, energy, and current

Answer: (B)

Ohm's Law fundamentally relates voltage, current, and resistance in an electrical circuit. This law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The mathematical representation of this relationship is expressed as V = I × R. This fundamental law is essential for understanding how electrical circuits operate, allowing engineers and technicians to calculate and predict the behavior of electrical systems. It provides a clear framework for analyzing circuit components and their interactions, ensuring proper design and troubleshooting of various electronic devices and systems. In this context, the other choices do not accurately represent the core relationship defined by Ohm’s Law. For example, voltage, power, and capacitance focus on different concepts that are not directly related to the specific relationship outlined by Ohm's Law. Similarly, power, current, and resistance incorporate power without including voltage, while voltage, energy, and current mix terms that are not part of Ohm’s Law, particularly the concept of energy, which is distinct from voltage in this context.
