hi, im new to the forum so im not sure this is the right category. any way. i have this circuit consisting of parallel and series resistors. the problem for me is that i cannot figure out how to add up all the resistors if you guys could help me to make rth, i think i should be able to do the rest. MY RLOAD IS R4 thanks
the sketch is there if u cant see it go to http://aycu25.webshots.com/image/36864/2006359725630909493_rs.jpg
http://www.allaboutcircuits.com/vol_1/chpt_10/1.html introduces circuit analysis. You can use any number of methods to arrive at your results.
When you say that R4 is the load, do you mean that you need to remove R4 and then calculate the Thevenin equivalent of all the rest?
Replace both voltage sources (V1 & V2) with nothing by removing them and then: Add up R6,R2,R3 in parallel. Add the parallel combination of (R6,R2 & R3) with R1 and R7 in series Good Luck You can solve this by using the superposition theorem too but that would be longer..
