According to Ohm's Law, how is current related to resistance and voltage?

• A. Current decreases as voltage increases
• B. Current is proportional to voltage and inversely proportional to resistance
• C. Current is independent of both voltage and resistance
• D. Current increases with decreasing voltage

Answer: (B)

The relationship described in the correct answer is derived from Ohm's Law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. This relationship is mathematically expressed as I = V/R. When voltage increases while resistance remains constant, the current also increases. Conversely, when resistance increases and voltage remains constant, the current decreases. This fundamental principle explains how voltage and resistance work together to influence the amount of current that can flow in an electrical circuit. The other options do not accurately represent the relationship defined by Ohm's Law. Some suggest that current behaves independently of voltage and resistance or that changes in voltage behave contrary to established electrical principles. Such claims do not align with the foundational understanding of electricity as outlined by Ohm's Law.
