Depends on the number of phases.

They both have the same current.
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
Both the bridge rectifier and the full-wave rectifier achieve the same thing. They rectify the AC input on both opposing phases so as to minimize ripple time and voltage. The difference is that a bridge rectifier consists of four diodes arranged in a bridge, so the input needs to only be single phase AC, while a full wave rectifier consists of two diodes, but needs a split phase AC source, such as provided by a center tapped transformer winding. Also, the bridge rectifier presents two junction drops in the output, because there are always two diodes in series, while the full-wave rectifier presents only one junction drop in the output, because there is only one. It is a trade-off.
A rectifier allows current to flow only in one direction. In a half-wave rectifier circuit, an input wave which oscillates between positive and negative, will 'pass through' the positive portion of the wave, and when the input is negative will output zero. A full-wave rectifier circuit, is commonly configured with 4 rectifier diodes, which allow a positive wave to output when the input wave is negative.
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.)
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.
to flow the electrons one way
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.
They both have the same current.
It is not really necessary for 2 diodes of full wave rectifier to be identical. However, it must be understood that the two diodes will have the same forward current, and the same reverse voltage, applied to them, so their ratings should be comparable.

No. For a full wave rectifier, you need two diodes and a center tapped secondary, or you need four diodes and a non-center tapped secondary.
No. Diodes are diodes. One diode can be USED as a half-wave rectifier. Four diodes can be used to build a bridge rectifier.
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.
Use a full wave rectifier with 6 diodes, as in a car alternator.
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
This depends on the current carrying capacity needed. I've purchased some for as little as $.30 (US). A full wave rectifier is really just four diodes, so it isn't typically an expensive component.
