What does Ohm's Law state about the relationship between current, voltage, and resistance in a conductor?

Ohm's Law describes a fundamental relationship in electrical circuits, highlighting how current, voltage, and resistance interact with one another. According to Ohm's Law, 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 relationship can be mathematically expressed as ( I = \frac{V}{R} ), where ( I ) is the current measured in amperes, ( V ) is the voltage measured in volts, and ( R ) is the resistance measured in ohms.

When the voltage increases while keeping resistance constant, the current increases, demonstrating the direct proportionality. Conversely, if the resistance of the conductor increases while voltage remains constant, the current decreases, highlighting the inverse relationship. This foundational principle is crucial for understanding how circuits operate and for applying electrical theory in practical scenarios.

Understanding this law is essential for anyone working with electrical systems, as it governs the behavior of circuits under various conditions.
