I wish I had a perfect DC voltage across the resistor but its still oszillating, pls help :)

I changed the voltage source to DC AND IT DIDNT OSCILLATE

You need a lot larger capacitor, try a 1mf.

the capacitor will still have a ripple, to remove it you can use a zenner, or make a voltage regulator with transistors

its imposible to remove completely the ripple...you would need a 1000 F capacitor and that would bring more problems than it solves

It depends on what the system load is, looking at the circuit as presented, the ripple with a 1mf capacitor is negligible. There have been circuits posted in the past that for all intents, have no ripple.

Use a voltage regulator.

You could get an almost perfect dc voltage if you used a voltage regulator like others have suggested since the regulator has a stable voltage output as long as the voltage never goes below the set threshold of the voltage regulator. An efficient voltage regulator could be a buck converter with feedback control using something like a 555 timer

Here we have only 1% ripple, so why do we need to increase the cap or use zener diodes or use voltage regulator or use even over engineered buck converter?
