    Finding potential difference across capacitor plates?

    Oops sorry. Well I meant that there will be a ratio when you divide one by the other; when transferring k over to solve for the unknown variable, there will be an actual number Anyways I'm still lost

    Finding potential difference across capacitor plates?

    So does that mean I let C=kε°A/d equal to each other so kε°A/d=kε°A/d? And then from that plug in 3.6 for one of the k, and 1 for the other? And from that, the k's will cancel, the A's will cancel b/c identical, and I'm not sure about the d's. Well is that the right method or am I still doing...

    Finding potential difference across capacitor plates?

    Homework Statement Two capacitors are identical, except that one is empty and the other is filled with a dielectric (k=3.6). The empty capacitor is connected to a -11V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric so that it stores...
