Hii
i heard that we wont get a shock even if 100 amps flow through us when voltage is very less.. im in full confusion.. Thanks in advance
Just to add some ideas: Your confusion is well-founded because the things you've heard have little basis in real-world situations. Or in the case of the above quote, are completely false.
1. If 100 amperes flowed through a human person, they would be shocked, and most likely die if the path were through vital organs.
2. It is likely that your confusion results from the fact that under certain circumstances, an individual could touch a conductor of a 100 ampere capacity (ampacity) and not receive a shock--because, for whatever reason, they do not become a path for the current. As in your comment, if the voltage were very small, you likely would not become a path for the current, in which case 100 amps would not flow through you. And because this oddity
can occur, you heard somebody (whose job it is to know better) tell you that 100 amperes may not kill.
This is technically true. As I type this, I sit not two feet from a 200 ampere
service. It has never shocked me yet, since all the conductive equipment is
enclosed and/or insulated. I intend to keep it that way.
This person should have told you what minimum amperages (with what voltages) are required to injure or kill. These amperages are a very small number, as the previous post so clearly illustrates.
3. Also what you need to know is that amperage and voltage are not the only things you need to concern yourself with. These values are often spoken of in terms that say "this amperage, x, or this voltage, y, is or is not a dangerous amperage or voltage. This is wrongheaded thinking. So often it is the guy like yourself, with limited knowledge (on the advice of another with similarly limited knowledge) who ends up being the statistic.
86-35 Maintenance worker electrocuted while replacing a ballast in a fluorescent light fixture. Conductor not deenergized, polarity reversed because of installation error.
86-36 Carpenter electrocuted when portable electric saw apparently developed a ground fault. Engaged in construction of laundry building for apartment complex.
These items, taken directly from a NIOSH report, illustrate that the average Joe Construction Worker can easily be killed (electrocution by definition is deadly) going about their tasks if they do not take proper precautions.
4. Another thing altogether is ArcFlash and ArcBlast. Just look these up. And choose video.
