    Question

    Which law states that the current through a conductor is

    directly proportional to the voltage across it?  
    A Newton’s Law Correct Answer Incorrect Answer
    B Ohm’s Law Correct Answer Incorrect Answer
    C Ampere’s Law Correct Answer Incorrect Answer
    D Faraday’s Law Correct Answer Incorrect Answer

    Solution

    Ohm’s Law: V = IR, where V = voltage, I = current, R = resistance.   It applies to metallic conductors at constant temperature.   If voltage increases, current also increases.   It’s widely used in electrical engineering and circuits.
