Consider two copper wires with the same cross-sectional area. Wire A is twice as long as wire B. How do the resistivities and resistances of the two wires compare?


Wire A and wire B have the same resistance.
Wire A has twice the resistivity of wire B.
Wire B has twice the resistance of wire A.
Wire A has twice the resistance of wire B.
Wire A and wire B have the same resistivity.
Wire B has twice the resistivity of wire A.

  1. 1. False.
    2. False.
    3. False.
    4. True.
    5. True.
    6. False.

    Note: The resistivity 0f both wires is the same, because they are made of the
    same material(copper).
