-
a capacitor consists of two metal plates separated
by an insulating material.
-
a capacitor can store an electric charge, and that
its ability to store a charge (capacitance) depends upon the area of the
plates and their separation.
-
3d.3 Understand that capacitors block direct current
but allow alternating current to pass by continuously charging and
discharging.
-
The effect described above of the current flowing
in a DC circuit until the plates are charged is used to effectively BLOCK
a DC current.
-
However, when an AC is applied to a capacitor then
the current continues to "apparently flow" due to the continuous charging
and discharging of the capacitor each cycle of the AC wave form.
-
larger values of capacitor may be polarised and must
be correctly connected.

Can you fill in the blanks?
