Capacitor circuits which smooth out rectified ac voltage are known?
You bet they are known. They are used all over the place, probably several in your house.
Why is voltage rating of a capacitor important to the user?
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
How can a capacitor reduce the effects of ripple voltage?
The smoothing capacitor converts the full-wave rippled output of the rectifier (which is left over AC signal) into a smooth DC output voltage A smoothing capacitor after either a half-wave or full-wave rectifier will be charged up to the peak of the rectified a.c. Between peaks of the a.c. the stored voltage will drop by a degree dependent on how much current is drawn from it by the load. The larger the value of the capacitor, the less drop there will be, and therefore less ripple when loaded.
What will the multimeter show if it is used to measure the voltage of the ac half wave rectified voltage?
rms value of voltage
What is a capacitor analyzer designed to read?
Capacitor voltage
How the capacitor removes the ripples from the rectified voltage?
During the AC cycle, the capacitor charges when the rectifier conducts, and maintains the voltage when the rectifier is not conducting.
Capacitor inductor circuit which smooth out rectified ac voltage are known as?
filter circuits

What type of capacitor is often used in power-supply circuits to filter the rectified AC?
The electrolytic capacitor is most often used in power supply circuits to filter the rectified AC.
What is the reliable smoothing capacitor for rectified 24VDC?
FOR A 24VDC it is best to install a 50v breakdown capacitor to ensure reliability
Will a capacitor lower voltage?
A: As soon as a DC voltage is applied the capacitor is a short or no voltage
Why is voltage rating of a capacitor important to the user?
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
Can capacitor increase low voltage to high voltage?
yes a capacitor can improve voltage by improving power factor
How does capacitor discharge while ac supply is on?
For part of the AC voltage wave, the capacitor will be above the source voltage, and will discharge until the AC voltage wave increases above the capacitor's stored voltage.
How can a capacitor reduce the effects of ripple voltage?
The smoothing capacitor converts the full-wave rippled output of the rectifier (which is left over AC signal) into a smooth DC output voltage A smoothing capacitor after either a half-wave or full-wave rectifier will be charged up to the peak of the rectified a.c. Between peaks of the a.c. the stored voltage will drop by a degree dependent on how much current is drawn from it by the load. The larger the value of the capacitor, the less drop there will be, and therefore less ripple when loaded.
Application of capacitor?
A capacitor in its simplest form is merely two electrically conductive plates separated by an insulator from each other. As such the capacitor will block any DC voltage from passing through it, up to the electrical dielectric strength of the insulator. The capacitor will accept a DC charge and an electrical field will exist between the plates of the capacitor. The capacitor will retain this charge until it either leaks away via the high electrical resistance of the insulator, or is intentionally discharged. When an AC or varying voltage is applied to a capacitor, a varying electrical field is set up between the plates of the capacitor. This will thus pass through the capacitor, and can be seen on the opposite plate. Thus, a capacitor will pass an AC voltage. Now,as to the question, " application of Capacitor". One of the oldest and most useful of capacitor applications is filtering or smoothing the output of an AC to DC power supply. In this supply, an AC voltage is rectified by a diode into a varying DC voltage. A capacitor is placed across the output, and serves to supply voltage or "fill in" the output whenever the output voltage is less than the capacitor. The capacitor subsequently recharges on the next cycle and repeats the process. Thus, the output voltage of the power supply is smoothed out.
Whats the highest voltage increase i can make when replacing a Capacitor?
you cannot increase the voltage by replacing a capacitor. A capacitor is a passive components it has no gain.
