Ohm's Law describes the relationship between which three electrical concepts?

Ohm's Law specifically defines the linear relationship between voltage, current, and resistance in an electrical circuit. According to Ohm's Law, the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, provided the temperature and other conditions remain constant. This relationship can be expressed mathematically as V = I × R, where R is the resistance.

Understanding this law is fundamental in electronics because it allows for the calculation of one quantity when the other two are known. For instance, if you have a circuit with a known resistance and you measure the current flowing through it, you can easily calculate the voltage.

In contrast, the other options either introduce concepts not related to Ohm's Law—like energy, power, or capacitance—or mix them in a way that does not align with the basic principles established by Ohm. For example, while power can be related to voltage and current (P = V × I), it is not a component of Ohm's Law itself, nor is capacitance part of the relationship that Ohm's Law describes. Thus, the correct answer focusing solely on voltage, current, and resistance is essential to a clear understanding of how electrical circuits function.
