Why Human body feel Electric shock ?? n in an Electric train
during running , We didnt feel any Shock ? why
Answer Posted / latika
Feeling electrical shock means closing of the circuit
through the human body. Current gets path through our flesh
and blood to the earth.
In electrically operated trains power is extracted from
overhead bus through a insulated system to run electrical
motors so there is no chance of getting electrocuted.
Moreover the train made of steel/iron is well grounded so in
case of insulation failure also there is no electrocution of
passengers. Because current chooses the easiest,shortest and
lesser resistive path to find the earth.
