2 am in Riyadh :D. Guys I'm gona say it again PLEASE CAN ANYONE TELL ME HOW A BRIDGE RECTIFIER WORKS!!!!!!!

Bridge rectifiers

There are several ways of connecting diodes to make a rectifier to convert AC to DC. The bridge rectifier is one of them and it is available in special packages containing the four diodes required. Bridge rectifiers are rated by their maximum current and maximum reverse voltage. They have four leads or terminals: the two DC outputs are labelled + and -, the two AC inputs are labelled  .
The diagram shows the operation of a bridge rectifier as it converts AC to DC. Notice how alternate pairs of diodes conduct.

EDIT: Attached another diagram.

Drop in voltage :D. If power is being lost than it's bound to have an effect!!!

The 22,000V thing, is it equally supplied to each of the lines.  Also, what's defined as p.d. betweeen the pair of wires, I don't get taht
