why, when birds sit on transmission lines or current wires
doesn't get shock?

Answer Posted / vijay

why because, firstly we shold know that voltage is known as
potential difference that means to flow the electrons from
one place to another we need the energy difference.that is
why we always use to measure the voltage in between two
lines or line to neutral for example the line to line
voltage is 415 and then the line to neutral will be 240
volts simply there is no potential difference occur in a
single line
when the bird stand on a single line having same
potential if it is having saame potential then potential
difference will be zero that is y if we touch the neutral
wire we wont get shock pd is zero if no pd no shock
