Still I am unable to understand the Current, Voltage and Ampere. Eventhough the the Power supply is of 24 Volts if the ampere is more it will kill the person. (This was told by one electrical engineer - But I am unable to understand). There are many things in this world we are unable to understand. This also one among those things.
Let us look forward for the reply from our learned members.

Current never kills a person it's voltage . Think a situation you are hanging in air with the help of a Current wire. Current will move on your body but it will not kill because there is not voltage differences between your body parts . You can see the bird siting on current wire but they do not die .
Same if your body is touching earth or any other electricity conductor materials , it'll make voltage difference b/w your body parts and can lead death . So it's clear that voltage differences kill a person not current .
If the voltage differences is just 24 V it can't kill a person but affect harm
I hope it'll clear you query !! if not revert same here

Electric Current Needed to Kill a Human
From India, Delhi
The quantity of Current is the one that decides the type of damage caused to the human body.
But the quantity of current is decided by the voltage & resistsnce of the victim at the time of contact.
QUANTITY OF CURRENT FLOW DETERMINES THE SEVERITY of shock
1 milli amps - Skin tingling
9 milli amps - Starts Freezing of muscles
30 milli amps - Breathing difficulty
75 milli amps - Breathing stops
100 to 200 milli amps - Ventricular Fibrillation of Heart

Attached is a ppt which is self explainatory.
I was invited to Govt College of Polytechnic where I delivered this for the professors. (Train the trainer). This was drive under Industry / Government Institutes Partnership programme.

I not think that this is a childish question... Cause if you just analyze the reply's given by our members also you can find the controversy... If you feels this is so childish question come up with answer supporting by technical explanations...
Again quoting the following sentence from another website... Can you just go through it and come up with your views...
Provided a much lower body resistance figure augmented by contact with a ring (a band of gold wrapped around the circumference of one's finger makes an excellent contact point for electrical shock) or full contact with a large metal object such as a pipe or metal handle of a tool, the body resistance figure could drop as low as 1,000 ohms (1 kΩ), allowing an even lower voltage to present a potential hazard:
E = IR
E = (20 mA)(1 kΩ)
E = 20 volts
Notice that in this condition, 20 volts is enough to produce a current of 20 milliamps through a person: enough to induce tetanus. Remember, it has been suggested a current of only 17 milliamps may induce ventricular (heart) fibrillation. With a hand-to-hand resistance of 1000 Ω, it would only take 17 volts to create this dangerous condition.
Be specific and try to give a positive response instead of just throwing negative comments... We are here to discuss issues and to bring out the best possible solution which will be beneficial to all... If you feel still it as a childish question please ignore and don't waste your precious time in replying...
Sorry for not responding to any of the reply’s... I will review and replying to all the replies after tomorrow... I am appearing to my exams and little bit busy in my studies... Thanks a lot to all for participation and giving excellent views...
I am very happy to see many reply’s to this thread...
Keep on sharing your expertise...
Will it not make any damage to the life or parts of body of the victim.
