why human body feel electric shock ? in an electric train during running, we didn’t feel any shock?
Human body feels electric shock when it becomes part of an electric circuit and current flows through it.
Current is the movement of electrons, which are negatively charged particles, from one point to another.
When a human body touches a source of electricity, such as a live wire or an outlet, it provides a path for the electrons to move from the source to the ground. This movement of electrons causes electric shock, which can be painful or even fatal depending on the amount and duration of current.
In an electric train, the current flows from the overhead wires, through the train, and back to the power source through the rails. The rails are connected to the ground, so they have the same potential as the rest of the ground.
Potential is the difference in electric charge between two points. When a human body touches the rails, there is no potential difference between the body and the rails, so no current flows through the body. Therefore, we don’t feel any shock in an electric train.
However, if we touch both the overhead wires and the rails at the same time, we would create a potential difference between them and complete a circuit. This would cause a large amount of current to flow through our body and result in a severe electric shock.
This is very dangerous and should never be attempted.I hope this explanation helps you understand why human body feels electric shock and why we don’t feel any shock in an electric train.
