    Question

    The I-V graph of three resistances R₁ ,R₂ and R₃

    is shown in the figure below. The correct relation between R₁ R₂ and R₃ is:
    A R₁ > R₂ > R₃ Correct Answer Incorrect Answer
    B R₃ > R₁ > R₂ Correct Answer Incorrect Answer
    C R₃ < R₁ < R₂ Correct Answer Incorrect Answer
    D R₁ < R₂ < R₃ Correct Answer Incorrect Answer

    Solution

    It states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant. Mathematically, current-voltage can be written as V = IR, where V = Voltage, I = Current, R = Resistance So when I is more R will be less.
