Homework Statement


Find ##v_0##
Circuit schematic with a 480 V source on the left feeding R1 = 20 kΩ in series with current i, then R3 = 80 kΩ in parallel, R4 = 60 kΩ in series, and R2 = 180 kΩ at the output with terminals labelled v_o.

Homework Equations


looking for which way is the best

The Attempt at a Solution


Using parallel and series resistor I have found that ##i=0.006 A## what should I do next?

Circuit schematic: 480 V source with R1 = 20 kΩ in series, current i shown, R3 = 80 kΩ shunt, R4 = 60 kΩ in series, R2 = 180 kΩ shunt across output terminals labelled vo.

What is the voltage drop across R1 ?

Added in Edit:
By the way: That current looks suspiciously low.
 
If you have i then you can find the potential drop across R1. Go from there.

Personally I'd probably have taken a different approach and transformed the source voltage and R1 into a Norton equivalent, absorbing R3 into it, then convert back to Thevenin and swallow up R4 too. That would leave a simple voltage divider at the end.
 
What I did is:
##180+60=240## than ##\frac{240*80}{240+80}=60## and than ##60+20=80k\Omega##

Yes, that's fine.
 
So I found that the voltage on ##R_1=120## so I have ##480-120=360## finding the current on ##R_{4+2}## is ##0.0015A## so the voltage on ##R_4## is ##90## and overall it is ##360-90=270##?

Correct!
