A full wave bridge rectifier converts AC (Alternating Current) into DC (Direct Current) with an AC component. To achieve DC only, the output of the bridge rectifier must have the AC component removed by bypassing it, usually with capacitors.
It consists of 4 diodes in a bridge format. During one half of an AC cycle, two of the diodes conduct and on the other half a cycle the other two conduct. Diodes allow current to flow in one direction only.

bridge rectifier is an electronics component that is used in a circuit to turn alternating current (AC) electricity into direct current (DC) electricity. Although there are single components that can perform this function, you can make your own bridge rectifier by creating a bridge rectifier circuit with four diodes. A diode is a radial component with a metal lead protruding from each end. The diode allows electrical current to pass in one direction, from the cathode, or positive end, to the anode, or negative end. By electrically connecting the four diodes, you can make your own bridge rectifier...

rectifier means convert ac to dc.using hwr effciency is less,but using fwr we get good effiency,because of using two diodes.the basic principle of rectifier is resonace
A bridge rectifier refers to a diode bridge of 4 diodes in a bridge configuration that provides some polarity of the output for either the polarity of the input or output.
bridge rectifier is the best rectifier.
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.
Yes, if the diodes that the bridge rectifier are rated for 230V in forward and reverse voltages. Normally you can do a search for the part number on the internet and get specs there.
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
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.
bridge rectifier is the best rectifier.
how to make a bridge rectifier on breadboard
Merits a diode bridge rectifier is simple to build
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
The simple principle of a rectifier is to convert Alternating Current (AC) to Direct Current (DC) it does this by only allowing the top half of the AC wave to pass through. The simplist rectifier is a Diode. If you place a Diode in line with an AC current you will get DC current. If you just use 1 diode it will be a really choppy DC current. The best bet is 4 diodes in a Bridge Rectifier configuration. This will give full wave rectification. even after you've rectified the wave, it's still wavvy, So then you have to filter it to get it nice and smooth like the DC current you might get out of a Battery.

give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
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
rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
