In a simple half-wave rectifier, during the positive part of the alternating wave the diode conducts, making the load voltage equal to the supply voltage. During the negative part of the alternating wave he diode blocks, making the load voltage zero.
Another explanation
For as long as its circuit is alive, any sine wave signal running at a certain frequency has the positive part of its wave immediately followed by the negative part of its wave immediately followed by another positive part of its wave, and so on.
A half-wave rectifier would basically eliminate the negative part so the output of the rectifier, as seen by the load that is connected to it, would receive a positive half wave voltage then a zero voltage during the negative half cycle of the waveform, then a positive half cycle again, and so forth.
A full wave rectifier does the same thing for the positive half of the cycle and then basically flips the negative part of the waveform to give the same output as the positive part, so you have a series of positive pulses. The signal, as seen by the load after the rectifier, never goes negative.

Why rectifier is not used in dynamo?
rectifier is not used because of damaged of problemAnswer.Because there's no need for that since the lamp on your bicycle can still work on the induced AC power.
What is single phase Controlled rectifier?
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
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.
How can capacitor smooth or reduce the ripple of the voltage produced by the rectifier?
when rectifier is on, the capacitor is almost transparent (it charges to the voltage provided from the rectifier) when rectifier is off, capacitor holds the peak voltage since it stored a charge during rectifier on time.
Is there any application where center tap rectifier is preferred over bridge rectifier?
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
Can a rectifier work either way?
if you are looking for the direction of rectifier than Yes. the rectifier convert the alternating current to one directional Direct current. It work as short circuit on the case of forward biasing and work as open circuit on the reverse biasing so it can work only in one direction.
Why silicon controlled rectifier doesn't work in reverse biased condition?
Because when reverse biased it behaves like any other rectifier/diode.
Why rectifier is not used in dynamo?
rectifier is not used because of damaged of problemAnswer.Because there's no need for that since the lamp on your bicycle can still work on the induced AC power.
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.
Which rectifier has good efficiency?
bridge rectifier is the best rectifier.
Why do we use rectifier kit?
Working the rectifier
Can a rectifier work on DC?
Well, yes. But it isn't much needed as DC is already DC.
What is single phase Controlled rectifier?
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
What is the difference between controlled and uncontrolled rectifier?
A simple rectifier is a diode. It only has two terminals and will only allow electron flow in one direction only. A controlled rectifier (SCR=silicon controlled rectifier) has a third connection (gate). Which as the name suggests, is a gate that controls at which point the rectifier will work. It therefore has a level of control.There are various types and you would need the application specification, to get the best use of them.
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.
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.
How can capacitor smooth or reduce the ripple of the voltage produced by the rectifier?
