Thanks, it was that fact that the charges must add up to zero due to plates being connecged that gave me my third equation.

Ok, thanks again for your help.

Thanks RTjones. I have tried this but am still not getting the answer. Did you get the final answers? Thanks again for any further help you can provide.

Thanks for this message ehild, can you give me a bit more detail on the steps I would need to do in order to get the final solution? Thanks again

Homework Statement Three capacitors C1–C3, all initially uncharged, are placed in the circuit shown. The capacitances are C1=8.9 μF, C2=20 μF, C3=12.2 μF, and the battery voltages are V1=18 V, V2=10 V, V3=18 V. What is the magnitude q1 of the charge on capacitor C1 once equilibrium has been...

Fantastic, thanks for all your help!

Thanks for your time in helping me out. I guess that's what is confusing me. That the rod cannot transfer the electrons to me (because it's an insulator) but it can transfer those electrons to the pitch balls. Am I missing something?

Thanks very much for the reply! That makes sense :-) But if it is not a conductor, how come when we brought that charged rubber rod to the pith ball it transferred it's charge to it? Thanks again!

Homework Statement When you rub a rubber rod with fur it becomes negatively charged. How does it keep it's charge if it's in your hand? Homework Equations The Attempt at a Solution We did this in the lab and it definitely stays charged (at least long enough to observe some...
