physics help?

A length of wire has a constant voltage between its ends. If the length of the wire increases, which of the following will also increase?

Update:

a)

resistivity of the wire

b)

current in the wire

c)

power delivered to the wire

d)

resistance of the wire

    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
