What is the function of a capacitor in the half wave rectification?
to smooth the output of the half-wave rectifier from 1/2 an AC cycle per period to a constant voltage.
How do you convert dc to ac current?
The AC current is fed into a rectifier, which is a set of four diodes that force the current at the output to be one direction. A capacitor across the rectifier output is then used to smooth out the voltage to a level higher than the desired DC output (eliminating, for example, the zero-voltage portions of the original AC sine-wave) A voltage regulator then regulates the voltage to a constant level.
Why use capacitor in circuit?
To smooth the output of the pulsating DC.
Why you use capacitor in a power supply?
The result of rectifying AC into DC produces a pulsating DC voltage. This is usually not acceptable. Capacitors store some of the energy, and release it during the time when the recftified voltage falls to zero. This smooths out the pulsations and produces a relatively smooth, constant DC output.
How does DC converts into ac?
A rectifier converts from AC to DC power by blocking one half of the AC current. A full-wave bridge rectifier is actually 4 rectifiers combined in such a way that it reverses the blocked half of the power, allowing it to flow through. A standard power supply consists of a transformer (for voltage changes), a rectifier, and additional components for cleaner power (e.g., filters to smooth out the waves of AC power, voltage regulator, etc.).

How do rectifiers and transformers work in a PC power supply?
There is no transformer used in PC power supply. There is rectifier used to rectify or convert AC input voltage into DC output voltage.Transformer based rectifier produces some spikes at the output DC voltage, hencethey uses SMPS (Switch Mode Power Supply) to avoid spikes to the output DC voltage and get a smooth DC voltage.

How does a power adaptor work?
it converts AC line voltage to DC low voltage. at first by transformer it setps-down the voltage then it rectified by bridge rectifier ckt. by this there is rippled DC output is there. then is this fed to filter circuit to filter the ripples and its given to regulator circuit to produce fine and smooth pure DC voltage. nowady SMPS (switch mode power supply) is use rather then older iron core transformers. SMPS have plenty of advantages over the Linear power adaptor. :))

What is AC ripple voltage?
Ripple voltage is when the DC voltage varies between (for example)12.5 Volts and 13.5 Volts, and does so rapidly. Technically, an alternator produces "alternating current", (hence the name, 'Alternator') and that AC voltage is converted to DC by running the current through a bank of "diodes". Diodes are able to allow current to flow one direction and not the other. As the voltage runs through the diodes it becomes a form of DC voltage, along with pulsations of up and downs, which is called as ripples. All electronic circuit require a steady DC supply free from these unwanted ripples. Fortunately, a battery when charged by pulsating rectified DC output can smooth out most of those ripples for us. If battery backup is not available in supply then filters ( reactive circuit elements, inductor in series and capacitor parallel to load) circuits can smooth out these ripples and improve quality of rectified output. BTW, it's called ripple voltage because when you look at the voltage on an oscilloscope it looks like ripples as the voltage varies.
What does smooth endoplasmic reticulum produce?
Lipids
What is the necessity of a filter in a rectifier circuit?
You use filters at the output of a rectifier to smooth out the pulsating DC. With no filter, the output would pulse between peak value (less diode forward drop) and zero. With a simple capacitor, the output would pulse between peak value (less diode forward drop) and some value that is the intersection between the discharge curve for the capacitor and the next forward conduction time of the diode. With a more complex filter, the output is progressively filtered, but that is beyond the scope of this question.
