What does Ohm's Law describe the relationship between?

• A. Current, voltage, and power
• B. Current, voltage, and resistance
• C. Voltage, resistance, and energy
• D. Power, energy, and current

Answer: (B)

Ohm's Law fundamentally 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 expressed in the formula \(I = \frac{V}{R}\), where \(I\) represents the current in amperes, \(V\) represents the voltage in volts, and \(R\) represents the resistance in ohms. Understanding this relationship is crucial for analyzing and designing electrical circuits as it provides a clear mathematical framework to predict how changes in voltage or resistance will affect current flow. The other options mention power and energy but do not accurately capture the primary components that Ohm's Law specifically addresses, making the understanding and application of current, voltage, and resistance essential in the field of electronics and electrical engineering.
