How to find equivalent resistance of this mixed circuit?

Find equivalent resistance, the current in R5, voltage across R2 and power of R10.

Actually, I don't know if my attempt is right. So, you would point out where there are mistakes, pleased.

R10 and R11 are in parallel: R10||11, also, R6 and R7 are in parallel: R6||7. Then R10||11 and R12 are in parallel: (R10||11)||12, then R9 and (R10||11)||12 are in series: R9+(10||11)||12. Then R9+(10||11)||12 and R13 are in parallel (R9+(10||11)||12)||13), then R1, R2, and (R9+(10||11)||12)||13) are in series: R1+2+(9+(10||11)||12)||13)...

And so on, until the circuit becomes this:

Then are R5 and R3 in parallel? If this is right I can continue myself. Another question, how to get current in R5 and voltage of R2? Kirchhoff's Rules ?

• Are the two ends of R5 and R3 connected to the same two nodes? If yes, then they're in parallel. Nov 15, 2019 at 19:39
• Are you familiar with converting between Thevenin and Norton equivalents? This would simplify the analysis considerably. Nov 15, 2019 at 19:54
• yea r5, r3 are parallel ! Then the ckt simplifies :-) Nov 16, 2019 at 20:46
