Homework Help: Equivalent Resistance of Circuit System

  1. Mar 16, 2014 #1
    I'm having trouble with this problem. Any advice would be appreciated. I know I can't group all resistors together in one loop, but I'm not sure where to draw my loops.

    Should I choose the 200 ohm and 300 ohm for one parallel and the 400 ohm and 80 ohm for the other parallel?

    I have a general understanding of series/parallel circuits, but this one is throwing me.

    Thanks again,

    You can make a single resistor with this one. The 200 and 300 ohm resistors are in parallel as are the 400 and 80 ohm resistors. The two equivalent resistors are then in series.

    Thank you analogdesign! I'm glad I was on the right track. =)
