i would to ask some i things i have trouble with understand it

**broken link removed**

the input tow line and the output tow line
so
when we talk about AC we know the wave is positive and negative
so what follow in the tow line with positive or negative

i need to know why in the bridge all wave still at positive even negative convert to positive

What Bridge?
Do you mean a Bridge Rectifier?

If So, It does Not convert Positive to Negative!

Typically it is wired to "Capture" the Positive of the sinewave to make a Positive DC Output.
If you Reverse these diodes in a bridge rectifier, It will Produce a Negative DC Output.

Or you can do Both at the same time.

** But What has this got to do with your Drawing?

may be my problem with the home wires

my home have to wires on adapter

what is this kind of wire
and when the sine wave going in this wire go on the one wire or booth
