24VACRMS * 1.414 = 33.94VACPEAK
The unloaded filtered DC voltage is 33.94V
The unloaded unfiltered voltage will be a single polllarity AC voltage with a peak of 33.94V

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.
Which type of rectifier has the greatest output voltage for the same input voltage and trasformer turns ratio?
Bridge Rectifier
What is a peak load voltage out of a bridge rectifier for a secondary voltage of 15 Vrms?
A: Peak voltage is RMS multiplied by a factor of 1.41
Difference between 4 diodes and 2 diodes rectifier?
a 2 diode rectifier is a center tap rectifier an a 4 diode rectifier will be a bridge rectifier *********************************************************** A two-diode rectifier is not always a centre-tap rectifier. If the two diodes are connected to the same end of a transformer's secondary, one by its anode and one by its cathode, one will proved a positive voltage with respect to trhe other end of the winding and the other will provide a negative voltage. (But perhaps that isn't considered a two-diode rectifier - but a two single-diode ones.)
What is the advantages of using the bridge rectifier over the center tapped rectifier?
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

What is the basic difference between a full wave bridge rectifier and a full wave center tapped rectifier?
A full-wave bridge rectifier with 4 diodes gives a dc output voltage equal to the average voltage of the whole transformer secondary. A FW rectifier with 2 diodes and a centre-tapped secondary gives an output voltage equal to the average voltage of half the secondary. If you have a 12-0-12 transformer, the bridge gives a 24 v output, while the 2-diode FW rectifier gives 12 v (approximately).

What is the formula for calculating Vrms for a bridge rectifier that is connected to a RC filter?

Why bridge rectifier is prefer over center type rectifier for low voltage applications?
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.
What is the peak inverse voltage rating of diode in bridge rectifier?
2x the peak supply voltage!
What is the formula for calculating DC votage from a 3 phase rectifier bridge using AC voltage across one phase?
A 3-phase rectifier bridge can be used with a single phase supply, it just means that four of the diodes are not connected. The peak voltage (if a reservoir capacitor is used) is sqrt(2) times the rms supply voltage and the average voltage using inductor smoothing is 0.9 times the rms voltage.
Why you are using the bridge rectifier in most of the circuits instead of full wave rectifier eventhough the output of both are same?
If diode in the bridge circuit becomes open the circuit will become a half wave rectifier instead, but if a diode in a full wave rectifier opens then the whole circuit becomes open. (No current flow). ************************************************************** The outputs of the bridge and the two-diode full wave rectifier are not the same. For the rectified voltage to be the same value, the two-diode full wave rectifier must be supplied from a centre tapped transformer winding, the total voltage of which is twice that necessary for the bridge rectifier circuit. Furthermore, the maximum d.c. which may be drawn from the centre tapped transformer/two-diode arrangement, assuming capacitive filtering, is the same value as the transformer secondary winding's capacity. In the case of the bridge, the maximum d.c. which may be drawn, also assuming capacitive filtering, is 62% of the transformer secondary winding's capacity.
Does a full-wave bridge rectifier results in a full secondary volatge at the output?
No. The voltage at the output is the full secondary voltage minus two diode forward bias drops. Depending on current and the specifications of the diode, this total drop could be between 1.5 and 4 volts.
What is the advantage of using the centre tapped full wave rectifier?
By using a center tap, with the tap connected to ground you can use one winding for the positive AC swing and the other winding (both relative to the center-tap) for the negative swing. Thus, when the secondary windings can be connected to the AC inputs of a full-wave-bridge rectifier to harvest a bi-polar DC power source. i.e. - a positive DC voltage 'rail' AND a negative DC voltage rail, say for example you have a 24VAC center tapped secondary of a 110VAC transformer. With a full-wave bridge, the center tap becomes the circuit 'ground' (aka 'return') in a DC circuit.
