how to convert ac to pure dc? Answered

I want to convert 5volt ac to 5 or less voltage!

i got  a transformer it gives out 5volts dc!

i used four diodes bridge !

but the current is still vibrating i came to know this by using a simple white led it vibrates!


although the diode bridge converts it to dc but not in pure dc format help me!!

can anyone give me a simple circuit to convert it to dc ( i have used diode bridge but it it is still vibrating i need some more out here to make it!!
 )

Hav0c's right!!.... see this.....

You just need to smooth your rectified output....and for this, you need to put in a RC filter......

Why does every sentence end with an exclamation mark!

Why is everyone so excited about nothing!

Connect a high-value capacitor in parallel with the output lines!

And use a 5-volt regulator to smooth the output!

Here's a link!

OKAY!
DON'T TAKE IT SERIOUSLY .
NOW FOR YOU I WILL PLACE A FULL STOP AT EACH END I USE EXCLAMATION MARK WHEN I AM IN A CONFUSIN SITUATION!
THANKS FOR YOUR REPLY!!

Eh, whatever. Let us knowhow this goes. You know how to use a regulator?

well i got a better option at wikipedia.
just look at this image it's a complete circuit!!
sorry for the exclamation mark but in my knowledge i not so irritating!

Well if you use a five-volt regulator like I showed you, you would get rid of those pulses up there and have a nice smooth pure DC source.

and i am only 14 and does not have components more than capacitors and resistors and other simple stuff!

I'm surprised that you can see the pulses since they are coming at 120 pulses per second. You may have something else wrong.

FIRST I HAVE ALSO ATTACHED A DIODE BRIDGE IT REDUCES IT'S PLUSES
I CAN'T WATCH DIRECTLY BUT THIS ACTION IS ELIGIBLE TO DISTRUB MY EYES I FEEL VERY DIFFICULT TO SEE IN THAT BLINKING LIGHT THOUGH IT'S VERY FAST!
THANKS FOR YOUR REPLY!

Just put a 470uF cap across the bridge.

try connecting a capacitor in parallel with it this should fix it
