WHAT DO U MEAN
I MUST TELL U THAT A CURRENT LESSER THAN 24 VOLTS CANNOT BE FELT BY US WE WILL NOT EVEN FEEL IT.
AND ALSO VOLTAGE IS NOT THE ONLY THING WE ALSO NEED TO KNOW WHAT IS POWER FACTOR AND HOW MANY AMPERES THE CURRENT IS

It is the current passing through the heart that causes the damage. Current is controlled by the voltage and the resistance. If the skin resistance is low because of wetness, or cuts, even a smaller voltage can give trouble. Generally, AC is worse than DC for the same voltage.
No minimum safe voltage can therefore be specified.

I did not understand the question,
Its either " What is the minimum voltage that human body can feel" or " what is the maximum voltage that human body can resist"
Actually its the electric current which flows through the body, so the value of the current and the power which determines the threshold values.
Minimum power: 0.01 Watts below which humans will not feel anything.
Maximum power: 0.25 Watts, above which it will be felt, but non-fatal.... above 100 watts is fatal.

voltage isn't the problem
the question should be:what is the minimum current that human being can resist?
a man could resist thousands of volts will low amps.

I assume you mean maximum!?
Up to a point, high voltage simply causes spasms, as it interferes with neural impulses, creating extra impulses etc...and so the damage done usually comes from a result of these spasms.
Current is what causes actual injury - by damaging or melting tissues. However current and voltage are linked, and for most purposes that we use electricity for, there will be sufficient current in proportion to the voltage.
I hope this makes sense, but i confess i don't know an actual figure as i am not a professional in this field.

Minimum? Should be 0 volts.

It is always better not to touch electric wires and let the job be done by trained personnel…
I think 6 to 9 volts would be ok...
12 volts (used in cars) gives some shock... beyond that you should not try...

Its not the voltage that kills you, its the Amps, or Current.

minimum..-:
there is no limit
maximum
also no limit
