# Suppose some electricity is flowing through a long straight wire without any insulating coating that gives an electric shock to a person at rest relative to the wire on touching it. Is there a speed with which if the person runs along the wire in the direction of current flowing such that he/she does not experience any shock?

I have completed my (B.Sc M.Sc Physics)..And Teaching @class 11,12 @Experience.= 5year

The person must have high velocity then drift velocity of the electron, which is practically not possible.

It is an excellent, thought-provoking question! Suppose a person runs along the direction of electron motion with the same speed of an electron. Then for him, electrons are at rest means zero current in wire for him. Now if he touches those electrons provided that he is touching the ground with bare...

It is an excellent, thought-provoking question! Suppose a person runs along the direction of electron motion with the same speed of an electron. Then for him, electrons are at rest means zero current in wire for him.

Now if he touches those electrons provided that he is touching the ground with bare feet, then there is a potential difference between his hands and ground. It will make electrons move inside his body towards the ground, and he will feel the shock. So no matter whether he is walking or standing, electrons will run through his body only when there is a potential difference.

One can always get a shock either he runs or in the rest as long as he touches the wire. If he is not touching, he won't get any shock.

No, you see getting an electric shock( or more generally passing of electrical current through your body) is independent of the relative velocity of the person and the current in the wire, there is no physical attachment there.

Never put yourself in a position whereby a muscle contraction would result in clamping your hand around a live conductor involuntarily if you are standing on a rubber mat or any other non-conductive material. You can touch a live electric wire with one hand without getting an electric shock.

Current always flows from higher potential towards lower potential, and it's independent of velocity. Therefore, the person will keep on feeling shocked even if he runs until he leaves ground potential.

In every section of the wire, electrons are present, so it is not the previous electron which needs to flow through our body where we go the core after running while touching the wire the electrons from that section will conduct to our body. There will always be current wherever we go or even if we stand...

In every section of the wire, electrons are present, so it is not the previous electron which needs to flow through our body where we go the core after running while touching the wire the electrons from that section will conduct to our body. There will always be current wherever we go or even if we stand due to the potential difference between the wire and Earth and due to the conducting nature of our body.

Your answer includes both physical as well as biological reason. First of all, a man cannot match the speed of a moving electron and secondly, it only needs 0.1 seconds for receptors in the skin to take the shocking message to the brain and for the brain to respond towards it. To skip this time for the...

Your answer includes both physical as well as biological reason. First of all, a man cannot match the speed of a moving electron and secondly, it only needs 0.1 seconds for receptors in the skin to take the shocking message to the brain and for the brain to respond towards it. To skip this time for the whole process is also unachievable for a man who is just running.

LEARNING IS EARNING, START LEARNING

Practically it is not possible, and the flow of current doesn't depend on the velocity.

Since the current is the flow of electrons and electrons are the fundamental particles of the universe, so all of the matter contains electrons and humans also (in the form of ions) that makes the person impossible to reach a speed relative to the current (flow of electrons) as ions are moving continuously...
