Concept explainers
A capacitor with plates separated by distanced is charged to a potential difference ∆Vc-. All wires and batteries are disconnected, then the two plates are pulled apart (with insulated handles) to a new separation of distance 2d.
A. Does the capacitor charge Q change as the separation increases? If so, by what factor? If not, why not?
B. Does the electric field strength E change as the separation increases? If so, by what factor? If not, why not?
C. Does the potential difference ∆Vc change as the separation increases? If so, by what factor? If not, why not?
