What is the relationship between volts, amps, and ohms in electrical circuits?

The relationship between volts, amps, and ohms in electrical circuits is defined by Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R). This fundamental principle describes how the voltage in a circuit is directly proportional to the current flowing through it and the resistance opposing that flow.

In practical terms, if you know any two of these values—voltage, current, or resistance—you can calculate the third. For example, if a circuit has a voltage of 12 volts and a resistance of 4 ohms, you can determine the current using the rearranged equation: I = V/R, which would give you 3 amps. Understanding this relationship is crucial for troubleshooting and designing electrical systems in aviation maintenance.

The other options do not accurately represent the fundamental laws governing electrical circuits. Kirchhoff's laws govern current and voltage in circuits but do not define the relationship in the same straightforward manner as Ohm's Law. Similarly, Newton's Law and the Laws of Thermodynamics are not applicable in this context; they pertain to mechanics and energy transformations, not electrical circuit relationships. Therefore, focusing on Ohm's Law is essential for anyone studying and working with electrical circuits in aviation
