The efficiency(n) of fullwave rectifier is defined as: n=DC output Power/AC input power But Power=V*I n=Vdc*Idc/Vrms*Irms But Vdc=2Vm/pi,Idc=2Im/pi ,Irms=Im/root(2),Vrms=Vm/root(2) (Im:Peak Curent) n=(4Vm*Im/pi^2)/(Vm*Im/2)=8/pi^2=0.812=81.2%. So efficiency of full wave rectifier is 81.2%

What is the role of center trapped transformer in full wave rectifier?
centre tap transform convert ac into full wave rectifeir dc .It needs only two diodes but efficiency is less.
What is the advantages of halt wave rectifier over full wave rectifier?
Half wave rectifier makes the the sinusoidal wave uni-direction only in one half cycle and leave the other but in full wave rectifier both the cycles are made uni-directional.
What are the advantages and dis advantage of full-wave bridge rectifier compared with two diodes rectifier?
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.
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.
Why full wave rectifier is preffered over half wave rectifier?
Efficiency is double in case of full wave rectifier.

What was the major factor for developing the full wave rectifier?
1. Efficiency of full wave rectifier is better than other rectifiers i.e, Efficiency()=81.2%. 2.It's Peak Inverse voltage (P I V)=2Vm.
What is the formula for rectification efficiency for full wave bridge rectifier?
It is defined as dc power delivered to the load to the ac input power from secondary transformer

What is the frequency of ripple components in the output of capacitor filter?
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
What is ripple factor of the Full-wave rectifier?
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
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.
Which provide more power and why full wave or half wave rectification?
full wave rectifier, because in half wave rectifier only one p-n junction diode Ans 2. In full wave rectifier both negative & positive cycles are rectified , but , in half wave rectifier only the positive or the negative cycle is rectified . That's why full wave rectifier provides more power .
What is the advantages of halt wave rectifier over full wave rectifier?
Half wave rectifier makes the the sinusoidal wave uni-direction only in one half cycle and leave the other but in full wave rectifier both the cycles are made uni-directional.
