Question

why should you not touch electrical application with wet hand

Because water is a very good conductor of electricity

Answer 2

We should not touch electrical appliances with wet hands because water is a conductor of electricity which supplies electric current to our body by which we can get a electrical shock. If the current is of very high voltage then we can lead to dead because of electric shock and high voltage supply of electric current to our body. Thus, we should not touch the electrical appliances with wet hands.
