we
all know that the current always choose low resistance path to flow.
In
case of neutral wire the resistance value is too much less approximate R=0.
why?
Because Neutral wire is come from the transformer, which secondary winding is
connected in star & that neutral wire is grounded to the earth so the
resistance of neutral wire is very less.
Best
grounding resistance in between 5 Ω
to 10 Ω.
Our
body is resistance between 1000-10000 Ω
(resistance vary because of body moisture, you wear ring or any metallic part
on your body).
The
our body resistance much higher than the neutral wire Hence when we touch the
neutral wire we don’t get electric shock.
