Final answer:
No, he will not get an electric shock. Insulators do not conduct electricity, so there will not be a complete circuit for the electric current to flow through.
Step-by-step explanation:
If a man places an insulating slab on the ground and puts a large aluminum sheet on top, he will not get an electric shock if he touches the aluminum sheet next morning.
Insulators, like the insulating slab, do not conduct electricity. Therefore, the man will not be able to complete an electrical circuit by touching the aluminum sheet. In order to get an electric shock, there needs to be a complete circuit for the electric current to flow through.
On the other hand, if the man was standing on the ground barefoot and touched a live wire while also touching the aluminum sheet, he could potentially get an electric shock. This is because the human body is a conductor and can complete the electrical circuit in this scenario.
