Ohm's law provides equations relating to which electrical parameters?

Ohm's law is fundamental in electronics, establishing a direct relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The law is typically expressed with the formula V = I * R, indicating that the voltage across a conductor is directly proportional to the current flowing through it, with the resistance being the factor that defines this relationship.

The correct answer identifies volts, amps, and resistance as the key parameters connected through Ohm's law. This provides a clear understanding of how changing one of these values affects the others in a circuit, allowing technicians to calculate unknown values when the other two are known. For example, if the resistance in a circuit is known, increasing the voltage will result in an increase in current, demonstrating the interplay between these three important electrical quantities.

Other options do not accurately represent the core parameters described by Ohm's law. For instance, power is related to voltage and current but is not a direct part of Ohm's law itself in its basic mathematical form. Similarly, frequency and capacitance are important concepts in electronics but fall outside the purview of Ohm's law, which focuses solely on voltage, current, and resistance.
