A rectifier is a device that contains diodes to convert an AC supply into DC. The resultant DC voltage has ripple on it at twice the source frequency, or six times the source frequency for a 3-phase rectifier. The subsequent filter is there to filter out the ripple to provide a constant dc voltage.
On power supplies the filter is often a series inductor, while on low-power supplies used in electronics the filter is a parallel capacitor. Additional components may be added to give extra pure DC is required.

4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
What is the difference between first order low pass filter and second order low pass filter?
in second order filter attenuation to the frequencies in stop band is higher then first order filters.
What is the difference between amplifier and rectifier?
A Re generator is a a circuit that repeatedly supplies current to a memory or display device. A amplifier increases the amperage of a signal or current.
When a 60 Hz voltage is applied to the input of half wave rectifier what is input freequency?
The relationship of the input frequency and output frequency in a half-wave rectifier is one-to-one.(For full-wave, its one-to-two.)The shape won't be the same, as the rectifier will only pass alternate half-cycles, but the apparent frequency will be the same.
What is the difference between with capacitor rectifier and without capacitor rectifier?
To know the difference between capacitor and non capacitor rectifiers one must study what is the function of filter part.the filter part consists of capacitors or inductors or combination of both. the output of a simple diode rectifier is pulsating dc which means it consists of both dc part and ac part. filters are used to remove the ac part from such an output. capacitor filter means that a capacitor is used for filtering out the ac part. non capacitor or inductor filter means that an inductor is used for filtering out the ac part. There is another type called pii filter where both inductor and capacitor are used. Pii filter is the best kind of filter available
Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less

Which rectifier types would be easiest to filter?
full wave
What is amplitude modulation detector?
a rectifier and low pass filter
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
Is there a difference between a filter and a filter element?
Nothing, they are the same thing.
What is the difference between a petrol oil filter and diesel oil filter?
Difference is capacity and the fuel type.
Difference between slow sand filter and rapid sand filter?
distinguish between slow and rapid sand filter
What is advantage of precision full wave rectifier over precision half wave rectifier?
Either less ripple voltage with the same filter capacitance, or similar ripple voltage with smaller filter capacitances (and thus physically smaller filter capacitors).
The difference between a transfer and a rectifier?
A transformer is basically used to step up or step down the main power supply. The rectifier is used to convert an alternating current (AC) or voltage to direct current (DC) or voltage.
What is the difference between a lawn mower oil filter and a car oil filter?
