Hi, please could someone help me clear up an issue I am having of whether or not voltage can kill you. I know there are numerous threads on this but they don't quite answer my question. This crops up all the time in lots of forums but I was wondering if I am missing something because as far as I am concerned voltage can NEVER kill you because it isn't anything physical.
If I understand voltage correctly then voltage is the difference in energy per charge between two points. Therefore voltage is simply a numerical description of the difference in energy per charge. It therefore surely cannot physically exist. Energy is real and charge is real but voltage is not a physical thing. How can a description of something kill you. Surely its the ENERGY that kills you?
Looking at an analogous situation, if you divide gravitational gravitational PE by mass then you get gravitational 'voltage' which is the energy per mass (instead of energy per charge). If you dropped a rock from a height it could kill you if it landed on your head. This is because the rock has mass and energy which are real things. To say that the energy per mass killed you would be ridiculous because it isn't anything real. Likewise, the energy per charge (voltage) surely cannot kill you?
Is what I have said correct or not?
Thanks for anyone who can take the time to respond.
