AC means Alternating Current. Alternating Current changes direction constantly, usually at 60Hz (US, Canada, and others) or 50Hz (UK and others).
AC current can flow through a capacitor, it's DC current that can't
DC is direct current, and is characterized by its steady flow of current. AC is alternating current. It is characterized by increases and decreases in the current.
The flow of electric current in an AC circuit is alternating, it flows one way then the other, with reference to ground.
capacitors allow ac current to flow.
The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.
A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.

Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
