if one diode is open circuited(a break in the circuit):
it will act as a half wave rectifier .only +ve or -ve 1/2 cycles available at o/p.
if one diode is short(more probable case due to burn out).
this place a short across source for one half cycle,may destroy circuit.

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.
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.
Can you make transistor with 2 diode?
Yes, if the transformer output is center-tapped; otherwise, no, a bridge rectifier requires four diodes, or six for three phase power. More technically correct, what we are talking about is a full-wave rectifier. A bridge rectifier is properly always four or six diodes.
Does the current rating of a diode change when it is used in a bridge rectifier EG A bridge made up from four 10 amp diodes would it have a different total current rating. DD?
A : A diode is an dumb animal he does not care how it is used all it cares is that its limitations are not exceeded
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 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 happens if one of the four diodes in s bridge rectifier is reverse?
four diodes
What is bridge rectifire?
A four diode circuit to change ac to dc
How much does a bridge rectifier cost to make?
Total cost to make a bridge rectifier is about Σ25. A bridge rectifier is an electrical device that converts alternating currents (AC) to direct current (DC). The process of bridge rectification is a simple one using four diodes, two AC and two DC wires, an AC source and pliers.
Is a battery charger a rectifier?
Inside a 12 volt battery charger, one of the main components is a transformer used to lower the supply voltage to 14 VAC. The other main component is the diode bridge. It is a full wave bridge network which uses four diodes for voltage rectification. The open circuit output of the battery charger is about 13.8 VDC. So, no a battery charger is not a rectifier but it used the process of rectification in its operation.
Is 2 diode without center taped can befull wave rectifier?
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.
What is the symbol of a diode?
The letter used is called a Reference Designation, and for a diode sometimes depends on what kind of diode it is. Most diodes use the letter D, as in D1, D2, D3. Zener diodes usually use the letter Z or much more rarely ZR or ZD (Zener Rectifier or Zener Diode). CR is an archaic designation that stands for Crystal Rectifier. LEDs may use LED1, LED2, etc. or just D1, D2, etc. A bridge rectifier (four diodes connected so AC fed into two leads results in pulsating DC from two other leads) uses BR for obvious reasons. AE7HD The letter symbol for the diode is D.
