What is the relationship known as that describes power, voltage, and current in a circuit?

The correct relationship that describes the connection between power, voltage, and current in a circuit is expressed by Ohm's Law. Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. This fundamental relationship is typically represented by the formula V = I × R.

Additionally, the power in a circuit can be calculated using the formula P = V × I, where P represents power, V represents voltage, and I represents current. This interrelationship is critical for understanding how electrical systems operate.

The Power Formula, while related to the calculation of power in a circuit, does not encompass the entirety of the relationship between voltage, current, and power as comprehensively as Ohm's Law does. Voltage Regulation focuses more on maintaining constant voltage levels in electrical systems rather than the foundational relationships among power, voltage, and current. Lastly, The Energy Equation typically refers to broader concepts relating energy consumption, conversion, and distribution, rather than the specific relationships found in electrical circuits.

In summary, Ohm's Law effectively illustrates the proportional relationships among voltage, current, and resistance while forming the basis for understanding
