Which three quantities are described as influencing current in a circuit according to Ohm's law?

• A. Voltage, Resistance, Current
• B. Voltage, Resistance, Capacitance
• C. Voltage, Capacitance, Inductance
• D. Current, Power, Capacitance

Answer: (A)

Ohm's law shows how current is determined by voltage and resistance, through I = V/R. This means the amount of current that flows depends on the voltage across the circuit and the resistance it meets; raise the voltage with the same resistance and the current increases, or raise the resistance with the same voltage and the current decreases. Capacitance and inductance don’t appear in this basic relationship—they influence current in time‑varying or reactive circuits, not the straightforward V over R rule. So the quantities that describe the relationship in Ohm's law are voltage, resistance, and the resulting current.
