Question

When we a touch an electric wire we conduct the electricity right.so the electricity passes from our body to earth.so what if we are in Air and touch the wire.do we conduct electricity then.and also tell me how our body filled with calcium sodium and other elements conducts electricity.

Answer 1

You might have seen birds sitting on high tension lines without any problem, it is so because they sit on a single wire thus they are at the same potential as the wire, and also that their claws are insulating in nature. But they die when their wings touch two wires simultaneously, resulting in a potential difference and allowing the current to pass through them, same applies to us humans also. For the same reason it is possible to maintain a live power line from a helicopter.

Inside your body are atoms that are made up of positively charged protons, negatively charged electrons, and neutrons (which are neutral). An atom with unbalanced charges will become either positively or negatively charged, and the switch from one charge to the other allows electrons to flow from one atom to another. This is what is referred to as electricity.
