Which law states that current through a conductor is directly proportional to voltage at constant temperature?

  • A Faraday's Law
  • B Coulomb's Law
  • C Ohm's Law
  • D Lenz's Law
Correct Answer: Option C — Ohm's Law
Explanation:
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, provided temperature remains constant. This relationship is expressed mathematically as voltage equals current times resistance.
