How does Ohm's Law relate voltage, current, and resistance?

Ohm's Law establishes a fundamental relationship between voltage, current, and resistance in an electrical circuit. According to this law, the voltage (V) across a conductor is directly proportional to the current (I) flowing through it and the resistance (R) of that conductor. This is represented mathematically as V = I × R, which signifies that if you know the current flowing and the resistance present, you can determine the voltage.

This relationship is vital for understanding how electrical components behave in circuits. For instance, if you increase the current while keeping the resistance constant, the voltage must also increase proportionally. Similarly, if the resistance increases while the current remains constant, the voltage will increase as well. This interplay is essential when designing and analyzing electrical systems to ensure they function as intended.

Other options do not accurately reflect the relationship defined by Ohm's Law. While some may touch upon concepts involving power and different mathematical manipulations of electrical parameters, they do not align with the core principle that voltage is the product of current and resistance.
