# How do I simplify this complex resistor circuit? [closed]

I have this circuit diagram and I need to find the current through the circuit.But I have no idea how to simplify this circuit.

I have tried applying Kirchoff's Current Law but could not do it.

Thanks for any help!

• Look closely. What does the top 3$\Omega$ resistor do? Solve that first, then redraw the circuit without it. May 10, 2016 at 5:49
• @CuriousOne Can you provide a little more details,please? May 10, 2016 at 5:55
• I can, but that's all the help you need. The reason why they are giving you this circuit and not a really hard one is so that you learn to develop strategies to solve the simple ones without much effort. May 10, 2016 at 6:00
• As a side note, unless you need an analytic solution, use of a Newton-Raphson backsolver (TK!Solver, or the R-package BB are two example) to iterate to an answer are a good way to solve circuits will tons of nodes. May 10, 2016 at 11:58

I took the liberty of redrawing this circuit for clarity. Can you take it from here?
