In electrical terminology, what does "ohm's law" express a relationship between?

Ohm's Law is a fundamental principle in electrical engineering that describes the relationship between current, voltage, and resistance in an electrical circuit. It states 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 can be mathematically expressed with the formula ( I = \frac{V}{R} ), where ( I ) is the current in amperes, ( V ) is the voltage in volts, and ( R ) is the resistance in ohms.

Understanding this relationship is crucial for analyzing and designing electrical circuits, as it helps predict how much current will flow at a given voltage and resistance. For example, if you have a higher voltage applied across a resistor, the current will increase proportionally, provided the resistance remains constant.

The other concepts mentioned in the other choices involve electrical parameters but do not reflect the specific direct relationship laid out by Ohm's Law. While frequency, capacitance, and power are all important factors in electricity and electronics, they relate to different principles or laws such as Kirchhoff's laws or the power formula ( P = IV ), but not specifically to Ohm's Law in the way that current
