Because a capacitor is ideal for storing energy over short periods, as in a reservoir capacitor in a power supply.

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.


How capacitor helps to improve the ripple factor?

A capacitor helps improve the ripple factor in power supply circuits by smoothing out the fluctuations in voltage that occur after rectification. When connected in parallel with the load, the capacitor charges during the peaks of the rectified voltage and discharges during the troughs, effectively reducing the voltage ripple. This results in a more stable DC output, which is particularly important for sensitive electronic devices. By minimizing the ripple, the capacitor enhances the overall performance and reliability of the power supply.


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?

Can capacitor increase low voltage to high voltage?

yes a capacitor can improve voltage by improving power factor


Can the voltage across a capacitor change instantaneously?

No, the voltage across a capacitor cannot change instantaneously. It takes time for the voltage across a capacitor to change due to the storage and release of electrical energy in the capacitor.


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.
