Hi Ahmed22. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif
My spectacles seem heavily fogged up this morning. But from memory a full-wave rectifier circuit comprises an AC source feeding a transformer, then either 2 or 4 diodes, and followed by a large capacitor in parallel with a resistor (the resistor representing the load).
If it needs 4 diodes then it's usually referred to as a bridge rectifier, and it delivers full-wave rectification.

See; http://en.wikipedia.org/wiki/Electronic_symbol
The mists of time also cloud my judgment.
My guess is that you have an AC source followed by a transformer, then a bridge rectifier, a storage capacitor and a resistive load.

The first part is the AC circuitry. The second half is the DC circuitry. Without a focussed image we really cannot guess at what joins the two parts.

It is probably showing an alternative load: you can operate the rectifier with a resistive load, or you can operate it with a large filter capacitor across that load. You get greater load voltage (i.e., greater average or DC output voltage) by using the capacitive filter.

WOW. What did you search for? I looked up "full wave rectifier circuit" with google and the first link described everything.
