Homework Help: Get the resistance for each wires

  1. Dec 8, 2005 #1
    One day when the familiy Jones is out and drives with his new car wonders Oskar why there is a lot of wires in the backwindow. The heat wires are parallelwired where the resistance is resistance free wired.
    Oskar and his father reads in the instructionsbook that the wires got a resistance 5.0ohm/m they are connected six times parallely and the lenght of each wire is 0.8 m

    Then I get the resistance for each wires is 0.8*5 = 4 Ohm

    But This is not the answer, the book says that the answer should be 6Ohm because two wires creates a parallelwiring with resistance 4 Ohm in every turn and 2Ohm as replacementresistance

    Can someone please explain to me how to do this ? :zzz: :zzz: :zzz: :zzz:

    Im really stuck...

    I do not understand the statement of your problem.

    Post your native language, perhaps there is someone here who could help you get a better translation.
