The op stated that R1 and R4 are in parallel.There's only one pair of resistors in parallel.
Yes. R1 and R4 are in parallel. Those are the ONLY two that are in parallel.The op stated that R1 and R4 are in parallel.
You are correct of course. Silly me, as you might have guessed, I didn't closely look at what I thought were two ground symbols.Yes. R1 and R4 are in parallel. Those are the ONLY two that are in parallel.
R2 and R3 are NOT.
We've all done it. And we will all do it again. And again.You are correct of course. Silly me, as you might have guessed, I didn't closely look at what I thought were two ground symbols.
On what basis are you removing R3?Work out the parallel resistance, (20K) then remove the resistor to ground (R3),and work out the current across the 90V supply, then work out the voltdrop across R2, subtract the 30V and that should be it...
Well, I guess we can give credit where credit is due -- he DID come back and answer one of the clarification questions that was asked. That's better than most!I'm sure glad Henry Jyrkinson will get a good grade after all the work he's done to solve this problem.
