• Consider two copper wires of equal cross-sectional area. One wire has 3 times the length of the other. How do the resistances of these two wires compare?
• 
  
• O a. The longer wire has 1/3 the resistance of the shorter wire. 
• 
  
• O b. Both wires have the same resistance.
• 
  
• O C. The longer wire has 9 times times the resistance of the shorter wire. 
• 
  
• O d. The longer wire has 27 times times the resistance of the shorter wire.
• 
  
• O e. The longer wire has 3 times the resistance of the shorter wire.
