    Which of the following is the correct formula for

    Joule’s law of heating?
    A H=IR2TH = IR^2TH=IR2T Correct Answer Incorrect Answer
    B H=I2RTH = I^2RTH=I2RT Correct Answer Incorrect Answer
    C H=V2RTH = V^2RTH=V2RT Correct Answer Incorrect Answer
    D H=IRT2H = IRT^2H=IRT2 Correct Answer Incorrect Answer

    Solution

    Joule's law of heating states that the heat produced (HHH) is directly proportional to the square of the current (III), the resistance (RRR), and the time (TTT).
