Question

On a visit that you made on a dry and hot day to the home of a relative where young children live, you observe that they are playing on the nylon carpet in the room where a very pleasant conversation takes place.
• At some point your attention is drawn to the fact that one of the little ones is heading towards a large metal object that is embedded in one of the walls. You try to attract the child's attention so that he does not touch said object.

1) TRUTH OR FALSE(WHY): The child is an electrical conductor, so he collected all the free electrons from the mat, now having an excess of electrons. When the child touches the metal, the leftover electrons will be transferred to the metal because it is a better conductor, so it will suffer a shock.

2) How would the situation change if:
... the object embedded in the wall was as small as a pin? How does the object's size affect the shock?
… It would have been a rainy day?

Answer 1

It is true as the child must have accumulated some charge while sitting or playing on a nylon mat due to rubbing and friction which cause the electron transfer between child and the mat. So, the child is now a conductor with some charge and if he touches any other conductor like metal in the wall, then the movement of charge will occur, thus constituting the current through him which may give electric shock to him.

The size of conductor does not matter since the amount of charge in child would not change by the size of conductor.
