    How Do Switch Operations Affect Capacitor Behavior in a Circuit?

    I'm still very confused. Don't we need either the potential difference or the charge of one of the capacitors to use the Q=CV formula to solve for the other? Kirchoff's voltage law says that the sum of potential differences around a closed network is 0 but I can't figure out what to do with...

    How Do Switch Operations Affect Capacitor Behavior in a Circuit?

    C1 was charged to 30mC because Q=CV and the potential difference across C1's plates were 10V right? So if the capacitor provides the voltage, does it start to act similarly to a battery? If yes, then would G.) be 30/8V? because C1 is 3/8 of the total C in the circuit? so then H.) 50/8V I.)...

    Work required to separate parallel plate capacitors

    Homework Statement A parallel plate capacitor with capacitance C is charged to a value q and then isolated. The separation between the plates is then tripled. What was the work required to separate the capacitors?Homework Equations U=1/2CV^2 Q=CV C=ε0A/dThe Attempt at a Solution...
