Which of the following best describes the relationship between voltage, current, and resistance?

The correct choice articulates Ohm's Law, which states that voltage is equal to the product of current and resistance. This foundational relationship in electrical engineering is expressed mathematically as V = I × R, where V represents voltage, I represents current, and R represents resistance. Understanding this relationship is vital because it allows engineers and technicians to manipulate electrical circuits effectively by calculating how changes in one parameter affect the others. For example, increasing the voltage will lead to an increase in current, provided that resistance remains constant. Similarly, this relationship also helps in designing circuits and troubleshooting issues within them.

The other choices do not accurately represent the established principles of electrical circuits. Remember, understanding the correct relationship between these parameters is crucial for anyone working with electrical power systems.
