Second what makes a capacitor "bigger" (in the sense of more capacity). If you take an electron away from a positive charge, it develops a voltage. The more the charges are separated, the higher the voltage is. So the voltage per charge of a capacitor goes up as the plates get more separate*, and the capacitance goes down.

How do capacitors aid in phase shift in AC circuits?
This is because capacitors have the ability to store and release electrical energy, which can delay the changes in current.
