How do capacitors work?

There are the two conductors (known as plates, largely for historic reasons) and there''s the insulator in between them (called the dielectric). The two plates inside a capacitor are wired to two electrical connections on the outside called terminals, which are like thin metal legs you can hook into an electric circuit.
