    d)  resistance of the wire, since R ≡ ℓ

    As length increases, the resistance increases

    As resistance increases, the current decreases

    Resistivity for the material stays constant

    As resistance increases, power = V²/R decreases with constant voltage)

    So it is only the resistance that increases with length of the wire
