No. The diode conducts during only 1/2 of the cycle, leaving
a big hole and no DC where the other half-cycle should be.

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
How many diodes are used to make a half wave rectifier?
You use a half-wave rectifier where the system design does not require a full-wave approach. Half wave rectifier output is used for running ac motors.
What happens to the output when one of the diode becomes open in full wave bridge rectifier?
The output degrades to a half-wave rectifier.
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.
How rectifier transformer convert ac to dc energy?
The transformer produces AC at the required voltage, and then one, two or four diodes are connected to it to produce pulsating DC, which is then smoothed to DC by a series inductor, or, in low-power supplies, by a parallel reservoir capacitor. A single diode is called a half wave rectifier because it passes the positive half of the wave and suppresses the negative. Two diodes in conjunction with a centre-tap on the secondary make a full wave rectifier, while four diodes can be connected as a bridge rectifier, which is also full-wave and does not need a centre-tap.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
Difference between 4 diodes and 2 diodes rectifier?
a 2 diode rectifier is a center tap rectifier an a 4 diode rectifier will be a bridge rectifier *********************************************************** A two-diode rectifier is not always a centre-tap rectifier. If the two diodes are connected to the same end of a transformer's secondary, one by its anode and one by its cathode, one will proved a positive voltage with respect to trhe other end of the winding and the other will provide a negative voltage. (But perhaps that isn't considered a two-diode rectifier - but a two single-diode ones.)

How many diodes in a bridge rectifier?
Bridge Rectifier DiodesIn a "bridge" rectifier there is 4 diodes In a "full wave" there are 2 diodes.In a "half wave" rectifier there is 1 diode.

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..
What is the difference between a one diode rectifier and a two diode rectifier?
A one diode rectifier is called a half wave rectifier and only allows current flow for the positive portion of the sine wave. A two diode rectifier, or full wave rectifier allows positive current flow during the positive portion of the wave as well as positive current flow during the negative portion of the sine wave. This results in a much cleaner DC power signal. The addition of a capacitor in the output circuit will clean up the signal very nicely.
Why you are using the bridge rectifier in most of the circuits instead of full wave rectifier eventhough the output of both are same?
If diode in the bridge circuit becomes open the circuit will become a half wave rectifier instead, but if a diode in a full wave rectifier opens then the whole circuit becomes open. (No current flow). ************************************************************** The outputs of the bridge and the two-diode full wave rectifier are not the same. For the rectified voltage to be the same value, the two-diode full wave rectifier must be supplied from a centre tapped transformer winding, the total voltage of which is twice that necessary for the bridge rectifier circuit. Furthermore, the maximum d.c. which may be drawn from the centre tapped transformer/two-diode arrangement, assuming capacitive filtering, is the same value as the transformer secondary winding's capacity. In the case of the bridge, the maximum d.c. which may be drawn, also assuming capacitive filtering, is 62% of the transformer secondary winding's capacity.
