A half wave rectifier is not as effective as a full wave rectifier. With a 1/2 wave, you are throwing away one hump of the sine wave...either positive or negative portion. With a full wave rectifier you get both humps...either positive or negative.
The resultant effective voltage is much greater with a full wave rectifier, because there is very little time when the voltage is zero. The half wave is zero for 1/2 of the cycle.

How can we Diode can be used as a rectifier?
A diode is used to stop the negative voltage swing in an AC signal, so you only get the positive portions.diode-rectifier
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
4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
Does the commutator of a DC machine act as a half-wave rectifier?
No.It act as fullwave rectifier
Is there any application where a center tap rectifier is preferred over a bridge type rectifier?
yes, where only 2 diodes can be used for fullwave rectification. this was the case with vacuum tube power rectifiers (e.g. 5U4 & type 80). these tubes shared a common cathode between 2 plates, the plates were connected to the ends of the secondary, the cathode supplied the rectified B+ voltage to the filter, the centre tap was grounded.
What is an full wave rctifier?
A fullwave rectifier takes A.C. voltage and makes low ripple D.C. out of it. The next step is a capacitor to smooth the D.C. and reduce the ripple. The rectifier is typically made of four diodes arranged in a diamond shape.The two cathode/anode junctions of the bridge takes in the A.C. and conducts the positive part of the A.C. to the two cathodes junction and the negative part to the two anodes junction configured diodes.
Formula for peak inverse voltage?
piv:the maximum value of reverse voltage across a diode that occurs at the peak of the input cycle when the diode is reversed-biased.
Which rectifier has good efficiency?
bridge rectifier is the best rectifier.
Guyz how much voltdrop do you expect to get when measuring across 1 of the fwd biased Si diodes when the circuit is a fullwave bridge rectifier if supplied with 12Vac load being 3673 ohms?
A; engineers assume .6 to .8 volts depending on current flow however Boltzmann constant can be applied if the current is fixed otherwise back to assuming.
Why in 4 diode full wave rectification you use bridge?
bridge is use in 4 diode fullwave rectification to allow complete cycle so that there will an output DC for both the positive and ndgative half-cycle of the input AC.
How does a centre tapped fullwave rectifier conducts?
If one have a centre tap transformer you only need two diodes to get full wave rectification, the anode of the both diodes to the two outside taps the cathodes together will form your Negetive and the centre tap is your Possitive
What important system consisting of diodes in converting ac to dc?
Halfwave or fullwave or polyphase AC to DC?
Why do we use rectifier kit?
Working the rectifier
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.
