Consider two copper wires with circular cross-sections and equal lengths.  One wire has 3 times the diameter of the other.  How do the resistances of these two wires compare?

• The thicker wire has times the resistance of the thinner wire.

• The thicker wire has 1/3 the resistance of the thinner wire.

• The thicker wire has 1/9 the resistance of the thinner wire.

• The thicker wire has 9 times the resistance of the thinner wire.

• The thicker wire has 3 times the resistance of the thinner wire.
