homework and exercises - I wonder why I cannot charge a capacitor with alternating current?



Why can't I charge the capacitor with AC? How do the plates block the flow of electrons with DC but not with AC.


Somebody told me that the DC is blocked by the capacitor, so the capacitor gets charge, but I could not get the actual concept about it.

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
