##### Electric current goes one direction.

MoHei. :)

I made draw to explain what i mean.

Electric current,,,i mean that direct current and alternative current,,,this current,,matter-flow,,, is same kind and goes same direction through wire after diode-systems,,,

So,,,before transformer this matter-flow comes one direction,,,goes through transformer and then goes forward through diodes,,,,

If i change transformer to loadet battery,,,first battery is full of charge,,full of electric,,,and when R use this loadet electric,,, battery comes empty,,,no electric-matter,,,,so it must be loadet again,,,charge,,electric comes then loading-systems,,through transformer,,from socket on the wall,,,,from far-away some power station,,,

So,,my conclusion,,,alternative current is not forward-backward motion,,,it is one direction motion,,,?

In the circuit with the half wave rectifier, your are correct. The current only flows on the primary (AC) side of the transformer when during the half cycle in which the DC current flows thru the diode.

In the circuit with the full wave rectifier, the current flows back and forth on both sides of the transformer, but the diodes only permit it to go one direction thru the load (resistor).

In the circuit with the center tap transformer, the current flows back and forth on the primary side and alternates between the two halves of the secondary side.

You cannot use a battery to power the primary of the transformer unless you you have a way to rapidly switch the polarity of the battery back and forth, like 60 cycles per second. The transformer secondary only provides output current when the primary input voltage is rapidly changing. Connecting a battery to the primary would make one short pulse of current in the output and then the primary coil would burn up because of too much dc current.

Hmm,,what i mean,,,

Energy flows one direction,,so i mean that electric current cannot goes forward and backward, but,, i cannot says now what is the alternative current theory that point which open this contradiction,,

Power, energy, goes one direction,,,

DC--clear
- energy motion goes same like direct current,,electricity,,(small matter particles motion).

AC--something contradiction,,?
We think that sine-wave,,electric current goes forward and backward,,but then Energy-motion is 0, zero.

Hmm,,sine-wave both side must electric-current,,energy flow,,(small matter particle motion) goes one direction,then energy-motion is not 0, zero.
