addition confusion

Hi, Isn't the additon of the 3 R outs voltages should equal 36 volts ?? Confused

thanks in advance

When I click on https://www.circuitlab.com/circuit/5472egdps5gj/prob-addition-voltage/ I get "Error 403: Forbidden". I'm logged in to CL so perhaps the circuit is not public?

Hello,

I found a couple of points for you to look at:-

1] There are too many GND elements to allow the circuit to work in the way (I think) you intend. Take off two GND elements, the one between R1 & R2, and the one between R2 & R3. You have just one GND remaining connected to "power-". This now defines the 0v reference at the neg side of the voltage source.

2] To find the voltages across each R (which is what I think you are looking for), set up the following 3 expressions in DC Solver:-

V(outPower)-V(outR1)

V(outR1)-V(outR2)

V(outR2)-V(outR3)

The 3 expressions are voltages across R1, R2 and R3 respectively. The 3 voltages should now total V(outPower).

Hope this gets you on to the next step!

Got it ! The multi ground edit was part of numerous testing xperiment...did not think it got saved, sorry for that

thanks
