Ohm's Law states that current is directly proportional to voltage and inversely proportional to what?

• A. Resistance
• B. Capacitance
• C. Inductance
• D. Frequency

Answer: (A)

Current follows from V = IR, so the current is I = V/R. That means for a given voltage, current changes inversely with resistance: higher resistance reduces current, while lower resistance increases it. If you double the voltage with the same resistor, the current doubles; if you increase the resistance, the current drops.

Capacitance and inductance don’t set this basic V-to-I relationship in a simple resistor. They affect how current changes over time or with frequency in AC circuits (through reactance and impedance), but the direct inverse factor in this context is resistance. Frequency matters mainly in circuits where impedance varies with frequency, not in the straightforward current–voltage–resistance relation.
