What principle does Ohm's Law explain?

Ohm's Law is a fundamental principle in electrical engineering that describes the relationship between voltage, current, and resistance in a circuit. It 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.

The correct choice indicates that current is directly proportional to voltage, reflecting the formula I = V/R, where I represents current, V represents voltage, and R represents resistance. This means that if the voltage across a circuit increases, the current will also increase, provided the resistance remains constant. This foundational relationship is critical when designing and analyzing electrical circuits, as it allows technicians to predict how changes in voltage will affect current and vice versa.

Understanding this principle is essential for tasks involving circuit analysis, troubleshooting, and ensuring proper function in electronic systems.
