Question

Which two fundamental electrical quantities are related by the Ohm's Law?

• A. Current and power
• B. Power and resistance
• C. Voltage and current
• D. Voltage and power

Answer 1

Answer:

C. Voltage and current

Ohm's Law relates voltage and current, stating that the current flowing through a conductor is directly proportional to the voltage applied across it, provided the resistance remains constant. Ohm's law states that current is directly proportional to voltage but inversely proportional to resistance. At constant resistance, current increases as voltage increases and vice versa. At constant voltage, current decreases as resistance increases and vice versa.
