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?
resistivity of the wire
current in the wire
power delivered to the wire
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
