Which of the following demonstrates the correct associations between the components of Ohm's law and their units of measure?

Ohm's law is a fundamental principle in electronics that describes the relationship between voltage, current, and resistance. According to this law, voltage (measured in volts) is equal to the current (measured in amperes or amps) multiplied by the resistance (measured in ohms). The correct association, therefore, is that resistance is measured in ohms and voltage is measured in volts. This aligns perfectly with the formulation of Ohm's law and reflects the standard SI (International System of Units) units used in electrical engineering.

In the correct answer, resistance and voltage are matched with their proper units: ohms for resistance and volts for voltage. This foundational understanding is critical for analyzing electrical circuits and is consistent with the established conventions in physics and engineering. The other options do not accurately align the units with the physical quantities they represent, which is essential to correctly applying Ohm's law in practical contexts.
