What is the relationship defined by Ohm's Law?

Ohm's Law establishes a fundamental relationship in electrical engineering, stating 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. This is mathematically represented as ( I = \frac{V}{R} ), where ( I ) is the current, ( V ) is the voltage, and ( R ) is the resistance.

The correct choice reflects this relationship accurately, emphasizing that an increase in voltage results in an increase in current, assuming resistance remains constant. Conversely, if resistance increases while voltage is held constant, current will decrease, illustrating the inverse relationship.

Understanding this principle is essential in various aviation applications where electrical circuits are involved, particularly in troubleshooting and circuit design, as it helps in predicting how changes in voltage and resistance will affect current flow. Mastering this law is crucial for anyone involved in aviation maintenance and operations, ensuring safety and functionality in electrical systems.
