0.287. I hope this is an academic question and not something you're thinking of using in a circuit; three more diodes are cheaper than the kind of filter you'll need to clean up the output of a half-wave rectifier - AND you throw away half the voltage the transformer is putting out!

What is TUF for half wave rectifier?
It indicate how well the input transformer is being utilized. It is given by the ratio of DC output power to the AC power rating of Transformer.
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.
What is the basic difference between a full wave bridge rectifier and a full wave center tapped rectifier?
A full-wave bridge rectifier with 4 diodes gives a dc output voltage equal to the average voltage of the whole transformer secondary. A FW rectifier with 2 diodes and a centre-tapped secondary gives an output voltage equal to the average voltage of half the secondary. If you have a 12-0-12 transformer, the bridge gives a 24 v output, while the 2-diode FW rectifier gives 12 v (approximately).
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.
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.

Why can't we implement the center tapped full wave rectifier without center tapped transformer?
A center-tapped transformer and two diodes can form a full-wave rectifier that allows both half-cycles of the AC waveform to contribute to the direct current, making it smoother than a half-wave rectifier. This form of circuit saves on rectifier diodes compared to a diode bridge, but has poorer utilization of the transformer windings. Hence we do not use centre tapping for full wave rectification.Ashish sharmaAstt. ProfessorHIET, Shahpur, kangra(H.P.)
How you determine ripple factor of a half wave rectifier?
when a.c convert in d.c then some components of a.c remain with it called ripple factor
What are advantages of bridge rectifier?
A bridge rectifier will rectify both halves of a sine wave and give "continuous output" through 360 degrees of the input. Oh, and you don't need a center-tapped transformer to use it.
Full wave rectifier using RC triggering circuit with diagram?
A full-wave rectifier (sometimes called a "bridge" rectifier) produces output current on both half-cycles of the input AC waveform. ******************************************** There are two types of full wave rectifier circuit. One uses four diodes in a "bridge"configuration and is fed from a simple transformer winding. The other uses two diodes and needs to be fed from a centre tapped transformer winding.
Why use half wave rectification and what are its advantages over full wave rectification?
A full-wave rectifier will provide an output through both the positive and negative halves of the AC sine wave. The half-wave rectifier will only provide an output for half the cycle. The filtered outputs of both rectifiers can be "smoothed" well, but the higher the load on the half-wave rectifier, the more the output voltage will vary across a cycle of input power. This results in higher ripple and makes regulation a bit more difficult. The full-wave rectifier will provide an output through both the positive and negative halves of the sine wave. It effectively "inverts" the negative half of the cycle and provides two "pulses" of power per cycle as opposed to one pulse per cycle for the half-wave rectifier. The full-wave rectifier might use a pair of diodes and a center tapped transformer, or might use four diodes in a full wave bridge configuration and a transformer with no center tap.
What is a half transformer and a half transformer?
a hole transformer
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.
What happens when one of the diodes is removed from the bridge rectifier?
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
