In Ohm's Law, what is the relationship between current, voltage, and resistance?

• A. Directly proportional
• B. Inversely proportional
• C. Independent of each other
• D. Dependent on frequency

Answer: (A)

In Ohm's Law, the relationship between current, voltage, and resistance is defined by the equation ( V = I \times R ), where ( V ) represents voltage, ( I ) is current, and ( R ) is resistance. This equation indicates that current (I) is directly proportional to voltage (V) for a given resistance (R). If the voltage increases while resistance remains constant, the current increases proportionately. Conversely, if the resistance increases while the voltage remains constant, the current decreases. This fundamental principle helps to understand how electrical circuits function, as it illustrates the direct link between the amount of voltage applied to a circuit and the current that flows through it when all other factors are constant. This understanding is essential for anyone studying electrical concepts in line construction or related fields.
