Homework Help: How would one connect three 9Ω resistors to get 12Ω?

    how would one connect three 9Ω resistors to get 12Ω??

    Statement
    -----------
    how would one connect three 9Ω resistors to get 12Ω??

    equations
    -----------
    i guess the relevant equations would be nothing more than series & parallel resistance connections..


    The attempt at a solution
    -------------------------
    I've tried all possible ways to connect them (only 4 diff ways I guess??). There is apparently a solution since its in my nephew's textbook.

    Hint -- you are going to have to cut the resistors in half with a fine saw...

    I can do it with 4. Are you sure you read the problem correctly?

    But I like Berkeman's answer better.
