I need help with a circuits problem. I am going to try to attach a picture of the diagram. I understnad the difference between parallel and series circuits; however, i am completely lost with this problem. You do not have to solve it, i just need to understand where to start.

Start with all the resistors in series - you can just add those together. Total resistance is just the sum of the ones in series $\Large R _{T} = R _{1} + R _{2} + R _{3}...$

OpenStudy (agent0smith):

Add up the ones in red circle, and you can replace them all with one resistor. Do the same with the yellow and replace with one resistor, and the orange.

Sorry about posting in the wrong subject. I understand what you are saying agent0smith. Thanks for the help

OpenStudy (agent0smith):

Once you do that, then you can use the parallel resistors formula $\Large \frac{ 1 }{ R _{T} } = \frac{ 1 }{ R _{1} } + \frac{ 1 }{ R _{2} } +...$
