Which statement correctly describes Ohm's Law?

• A. Current is directly proportional to voltage and inversely proportional to resistance
• B. Current is inversely proportional to voltage and directly proportional to resistance
• C. Current is independent of resistance
• D. Current is directly proportional to capacitance

Answer: (A)

Ohm's Law links current, voltage, and resistance with the simple relation I = V / R. This means current increases when voltage rises and remains the same or increases only if resistance is constant; it decreases when resistance goes up for a given voltage. So describing current as directly proportional to voltage and inversely proportional to resistance captures this fundamental balance: higher voltage pushes more current through a fixed resistor, while a higher resistance restricts it.

If voltage doubles while resistance stays the same, current doubles. If resistance doubles with the same voltage, current halves. That clear dependency is what Ohm's Law conveys.

The other ideas don’t fit this simple resistor scenario. Current isn’t independent of resistance, and it isn’t inversely related to voltage. Capacitance isn’t part of Ohm’s Law for a resistor; capacitors relate to i = C dv/dt, which is a different situation involving time-dependent behavior rather than the straight V and R relationship.
