    2 diodes connected back to back ....and 2 anti-parallel diodes....are these 2 configurations same...i mean work similarly?....i think NO....rectify me please if wrong......it might be a silly question but i would really appreciate the answer

    So that whichever way current tries to flow, there will always be one diode which blocks the current? Draw it and try it.

    in back to back connected diodes...current will never flow...right?

    Yes, that is so.

    Yet there may be times when you do see a pair of diodes ("Zener diodes") connected exactly like that: back-to-back. What is this about?

    Sir,i have seen that in double sided clipping circuits..so that output is between (Vz.+Vk) and - (Vz.+Vk)..actually my question arose from there

    Careful..never?....zener back to back make a voltage regulator
    Rectifier diodes are sold back to back as a high frequency smps rectifer using the center point as the AC location, and signal diodes are connected back to back as a decision point (probably not the right term) but I see them all the time.
    The latter two are 3 terminal circuits, so without context, the question could be misleading.
