Which statement best describes Ohm's Law?

• A. Voltage is directly proportional to the resistance
• B. Current is inversely proportional to the voltage
• C. The current is directly proportional to voltage and inversely proportional to resistance
• D. Resistance is the cause of electric fields

Answer: (C)

Ohm's Law can be mathematically expressed as \( V = IR \), where \( V \) represents voltage, \( I \) represents current, and \( R \) represents resistance. The law indicates that the current flowing through a conductor is directly proportional to the voltage across it, provided that the temperature remains constant, and inversely proportional to the resistance within the circuit. This means that if the voltage increases, the current will also increase, assuming resistance remains constant. Conversely, if the resistance increases while the voltage is kept constant, the current will decrease. This relationship emphasizes the balance between these three quantities in an electrical circuit. In practical terms, a higher resistance in a circuit for a given voltage leads to less current flow, demonstrating the inverse relationship with resistance. Overall, this clear and concise depiction of the interplay among voltage, current, and resistance makes the selected statement the best representation of Ohm's Law.
