Homework Help: Simple resistance circuit prob

  1. Sep 6, 2004 #1
    Ok, this problem is bugging. I have to find the total equivalent resistance.
    I have included a picture below. There are numbers to this problem, but I want to figure out how to do this in terms of variables first.

    First I added R3 and R4 in series
    R34=R3+R4

    Then I figured out R234= 1/[1/R2+1/R34]

    Next I got R1234 = R1+R234
    ------- *
    Now this is where I got stuck
    I know the remaining three resistors are in parallel with each other.
    I tried doing 1/[1/R5+1/R1234+1/R6], but that didnt seem to work.

    Whats the correct procedure to go about this after the *?

    This last statement is wrong. R1 is connected in parallel with R234. I redrew your circuit, maybe this helps.
