Note: The assumption is that the appliance or device operates until the last coulomb 
      is used. 

28. Given that rho for copper is 1.724x108 ohms/meter, how much resistance does 
    100ft of 14AWG copper wire have? What does AWG mean?   Does wire diameter
    increase or decrease as the AWG number increases?
    Ans: 0.253 ohms
