i think not.
diodes have a low breakdown voltage, around 1v. a diac has bv of about 30v.

What are the classifications of diodes?
a diode is a device that alows current to flow in one direction you have power diodes which are used in rectification processes and high current operations but the two main families of diodes are solid state diodes or valve operated diodes.
What was the major effect of replacing the two diodes with resistors?
As I have no information on the circuit I can make no valid predictions as to the effect of replacing diodes with resistors. However I assume the effect(s) will resemble that of having very defective diodes in the circuit.
How will you differentiate the diodes whether it is zener or an avalanche when you are given two diodes of rating 6.2V and 24V?
Silicon "zener diodes" with a zener voltage rating of 5.6V or higher operate mainly by avalanche breakdown, so both the 6.2V and 24V "zener diodes" are avalanche breakdown type (not zener breakdown type).
Can full wave rectification be done by two diodes?
Yes, if the transformer secondary is centertapped.
Are diodes only used in a dc circuit?
There are lots of diodes - a "diode" is simply a device that has two electrical connections.If you refer specifically to the rectifying diode, it is used to convert AC current to DC current - so, it is used in a circuit that has BOTH AC and DC.
What is function of DIAC?
A DIAC is a diode alternating current switch. Its construction consists of two back to back diodes. It is usually used for triggering TRIACS.
What is an antiparallel?
An antiparallel is a line which forms equal angles with two other lines but in opposite directions.
What is an antiparallel force?
When it is not parallel. Parallel is when it is two straight lines: like train tracks are antiparallel, when it is going of course: Like a trapezium.
How does a Diac work?
A DIAC operated with a DC voltage across it behaves exactly the same as a Shockley diode. With AC, however, the behavior is different from what one might expect. Because alternating current repeatedly reverses direction, DIACs will not stay latched longer than one-half cycle. If a DIAC becomes latched, it will continue to conduct current only as long as there is voltage available to push enough current in that direction. When the AC polarity reverses, as it must twice per cycle, the DIAC will drop out due to insufficient current, necessitating another breakover before it conducts again
Can you use Diac and Triac for dc supply?
The diac conducts in both directions at approximately the same voltage, making it unsuitable in an AC to DC supply. The triac also conducts in both directions, based on a gate voltage which is slightly different in the two usable quadrants. That is why the diac is often used to trigger the triac - it makes the two conduction cycles more symmetric. In both cases, the diac/triac does not make sense for an AC to DC supply, but it works well in an AC voltage regulator, such as a lamp dimmer or motor speed controller.
What does antiparallel mean?
Anti-parallel means the sides of the DNA double helix.
What are the classifications of diodes?

Why dont we get the transister action by connecting two diodes back to back?
Because two diodes is not a transistor. There is an interaction between the junctions in the transistor, because of their proximity, that you don't get in the two diodes. The only use of modeling a transistor as two diodes back to back is to test a transistor with a multimeter as a quick go-nogo test for basic operability.
What is a true statement of diodes?
There are several types of diodes; the only thing they have in common is that they have two electrodes - hence the name.
What types of diodes are used in high frequencies?
Two types used at microwave frequencies are gunn and PIN diodes.
What is true about diodes?
Lots of things are true about diodes. There are different types of diodes; their general characteristic is that they have two electrodes (electrical contacts). They conduct current in one direction only.
Diodes have two connections name them?
Anode and Cathode.
