When building a bridge rectifier how do you choose the right size diode?

By figuring out how much amperage you wish to pass through the diode. If for instance you are building a battery charger and the transformer would normally supply 10 amps, you would select a diode (or diodes in parallel) that would handle at least 10 amps. You would normally select diodes that are at least 125% of the current desired. In this example you would select a diode that would handle at least 12.25 amps. It is better to use a rating of 150% for a safety margin.

Why transfer characteristics cannot be obtained for a bridge rectifier?
Its because one of the diode gets shorted.The diode in the left lower arm in a bridge rectifier gets shorted by the ground points of both the cro and the function generator.
What is the peak inverse voltage rating of diode in bridge rectifier?
2x the peak supply voltage!
What happen if all the diode in bridge rectifier is reversed?
it will work as a rectifier . because the AC current to be rectified will not be effected by this change. the out put DC polarity will be changed.
Why tunnel diode differ from the rectifier diode?
tunnel diodethe doping level of the tunnel diode is high when compared with the rectifier diodeit exhibits negative resistancerectifier diodethe doping level of rectifier diode is low when compared with the tunnel diode
What kind of diode that has 4 legs?
This is stupid question, how about how many leg are there in 4 way bridge rectifier. the answer is 4 legs.
What are merits and demerits of bridge rectifier?
Merits a diode bridge rectifier is simple to build
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.
Why transfer characteristics cannot be obtained for a bridge rectifier?

Purpose of bridge diode in a power supply?
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.
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.)
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.
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.
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
Are diodes rectifiers?
No. Diodes are diodes. One diode can be USED as a half-wave rectifier. Four diodes can be used to build a bridge rectifier.
What is the peak inverse voltage rating of diode in bridge rectifier?
2x the peak supply voltage!
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.
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
