• 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.
