A parallel-plate capacitor with plate separation d is connected to a battery that has a potential difference . Without breaking any of the connections, insulated handles are used to increase the plate separation to 2d.
a. Does the potential difference change as the separation increases? If so, by what factor? If not, why not?
b. Does the capacitance change? If so, by what factor? If not, why not?
c. Does the capacitor charge Q change? If so, by what factor? If not, why not?
