Homework Help: Need help with resistance number conversions

  1. Jul 18, 2009 #1

    I am not an EE, but I need help with a puzzle that has a resistor in it. The solution will look something like this:

    ?? ??.???
    ??? ??.???

    Thank you for your help,

    Yes, have a look at the following site which deals with resistor color codes:

    You can work out the values of the resistors from the color bands on them.

    Not sure what the puzzle is. Maybe you need to know the resistor values.

    Do you perhaps want the sum of the resistances of the two resistor strings? All of the resistors seem straight forward except the last one in the first row, which I have never seen. It perhaps is a resistance less than 10 ohms: For example, a red-black resistor may be the same as a black-red-black resistor for a 3-ohm resistor.
