You have a parallel plate capacitor (with air between its plates) which is attached to a voltage source until the capacitor is fully charged.

(a)After detaching the capcitor from the voltage source, you move the capacitor's plates farther apart; which of the following will occur (check all that apply)?

a.the capacitor's capacitance will increase

b.the capacitor's capacitance will decrease

c.the capacitor's capacitance will remain the same

d.the magnitude of the charge on each of the capacitor's plates will increase

e.the magnitude of the charge on each of the capacitor's plates will decrease

f.the magnitude of the charge on each of the capacitor's plates will remain constant

g.the potential difference across the capacitor's plates will increase

h.the potential difference across the capacitor's plates will decrease

i.the potential difference across the capacitor's plates will remain the same

j.the potential energy stored in the capacitor will increase

k.the potential energy stored in the capacitor will decrease

l.the potential energy stored in the capacitor will remain the same

m.more information is needed to be able to answer this

(b)While the capacitor is still attached to the voltage source, you move the capacitor's plates closer together; which of the following will occur (check all that apply)?
