What is the basic principle of Ohm's Law?

• A. Current is inversely proportional to voltage
• B. Current is directly proportional to voltage and inversely proportional to resistance
• C. Resistance is constant regardless of voltage
• D. Voltage is independent of the current

Answer: (B)

The basic principle of Ohm's Law states that 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 is mathematically expressed as \( I = \frac{V}{R} \), where \( I \) represents current, \( V \) represents voltage, and \( R \) represents resistance. This principle highlights how increasing voltage will increase current flow, provided the resistance remains constant. Conversely, if the resistance increases while the voltage remains the same, the current will decrease. Understanding this law is fundamental in electrical engineering and circuit analysis, as it allows engineers and technicians to predict how electrical components will behave under various conditions. Other statements do not accurately reflect the relationships outlined in Ohm's Law. For instance, the idea that current is inversely proportional to voltage does not align with the direct proportionality described in Ohm's Law. Additionally, suggesting that resistance remains constant regardless of voltage overlooks factors like temperature changes that can affect resistance. Finally, the notion that voltage is independent of current contradicts the core relationship established by Ohm's Law itself. Thus, the correct choice provides a comprehensive understanding of the interplay between voltage, current, and
