How is "Ohm's Law" defined?

Ohm's Law is a fundamental principle in electrical engineering and physics that quantitatively relates the voltage across a conductor to the current flowing through it and the resistance of that conductor. According to this law, the current (I) in a circuit is directly proportional to the applied voltage (V) and inversely proportional to the resistance (R). This relationship can be expressed with the formula I = V/R.

When the applied voltage increases while maintaining the same resistance, the current also increases, illustrating the direct proportionality. Conversely, if the resistance increases while keeping the voltage constant, the current will decrease, demonstrating the inverse relationship.

This combination of proportionality creates a clear framework for understanding how electric circuits operate, making it essential knowledge for studying electronics and related fields. The phrasing of the correct answer accurately captures this relationship, linking voltage and current while accounting for resistance.
