The process of conversion of AC into DC is known as rectification device used for this purpose is called as rectifier.A PN diode conducts well when it is forward biased and does not conduct Negligible current when it is reverse biased.This unidirectional nature of diode is used for the purpose of rectification.

Why a full wave rectifier is preferred over a half wave rectifier?
The a.c. component, or ripple, produced by the 4-diode (full wave) bridge rectifier is the same as that produced by the 2-diode full wave rectifier. The bridge is connected across the secondary winding of a transformer. The 2 diodes of the other type of full wave rectifier are each connected to one end of a winding, but that winding requires a center tap. For any desired value of d.c. after rectification, the a.c. voltage of the 2-diode rectifier winding has to be twice that of the winding required for the bridge.
Why in 4 diode full wave rectification you use bridge?
bridge is use in 4 diode fullwave rectification to allow complete cycle so that there will an output DC for both the positive and ndgative half-cycle of the input AC.
What is the use of bridge rectifier?
Most of the circuits comprising of electronic components run on dc supply.. As DC supply is not available directly for us, we use either 230/12V or 230/18V transformer to stepdown the available 230V (in some countries it is 110v) and then convert it into dc using a rectifier. As a bridge rectifier is more efficient than a conventional full wave rectifier, about 81.2%, it is widely used in such type of circuits.
What are advantages and disadvantages of p-n junction?
We can use it as a rectifier and switch
Why full eave rectifier rectifies negative half cycle?
the rectifier is Mainly used to convert the Ac current into DC current .In rectifier there are two diodes or (4 Diode In full wave bridge rectifier )are use is to conduct the current one is connected in forward bias(i.eD1) and the other is connected in reveres bias(i.eD2). As we know that the diode is conduct the current throw it When it is connected in forward bias . now when the voltage is applied to the circuit the the AC Current is start to flow throw circuit and in Positive half cycle of Ac current the Diode is Allow the current Pass throw it and during the Negative half cycle the Diode D2 is allow the current pass throw it and in these way the rectifier rectifies positive As Well As the negative half cycle
Why use the PN junction diode in rectifier?
We use pn junction diode in rfctification as a rectifier becase it allows current to flow in one direction only, i.e. in forward biase only , and stop current to flow in reverse baised. thats why we use pn junction diode in rectification.
How is AC converted to DC and does it change the power an item would have?
you basically use rectifiers..like zener diode rectifier and full bridge rectifier..
Why to use four diodes when two diodes also can serve the purpose in bridge rectifier?
Four diode rectifier not require a center tapped transformer.

What is the advantages of using the bridge rectifier over the center tapped rectifier?
you only use half the number of windings in the bridge comparing it to the center tapped , and in the bridge rectifier the peak inverse voltage that a diode must be able to sustain without break down is half of that in the center tapped PIV per diode: center tapped: 2Vm : bridge : 1Vm
What is the use of a bridge diode in an electronic circuits?
A Diode, or a Bridge Rectifier is a electrical component that blocks electron flow in one direction, but allows it to flow in the other direction. Usually made out of a Semiconductor called Silicon, A diode has an infinite amount of applications, but the most common is a Full Wave Bridge Rectifier. this device converts Alternating Current into Direct Current with 100% efficiency (except for the 1.4 volt drop between Diodes).
What does an alternator diode rectifier do?
The alternator diode rectifier converts the AC current being produced by the alternator to DC from which most of the electronics installed and battery use.
Why in 4 diode full wave rectification you use bridge?
bridge is use in 4 diode fullwave rectification to allow complete cycle so that there will an output DC for both the positive and ndgative half-cycle of the input AC.
Can you use transistor as a rectifier?
No, a Transistor operates with a modulated direct current. You need 4 Diodes to manufacture a rectifier to deliver direct current at the outlet, with alternating current at the input. A Diode is effectively a one way valve to address one halve of the cycle of the alternating current.
Why bridge rectifier is prefer over center type rectifier?
it is more preferable over center tapped rectifiers because you dont have to use special centre tapped transformer that has larger secondary windings thereby reducing the size and cost it also has another advantage by the use of 4 diodes i.e. peak voltage sustained by each diode is half of that sustained by the diodes in center tapped system that uses only 2 diode. thus lifespan of bridge type rectifier is more.
