Question

how do we feel objects? do electrons play any role in this?.... give reason for ur answer

Answer 1

It depends. Our skin, when dry, is non-conducting. It is an insulator, just like rubber. This means that the electrons in the tip of our finger are bound to the atoms and can’t freely move around. So, on this simplest level, when you touch an electrically neutral object, no electrons should be exchanged.
But, of course, these matters are seldom simple. As you approach an electrically charged object, the electric field increases inversely with the decreasing distance. At some point the field from even a small charge will be so high that it creates an electric spark through the thin barrier of air and in such case there will be an exchange of electrons. Likewise, if you touch a conductor with wet hands, the resistivity of your skin will be drastically reduced and current can flow through your skin. In fact, if the current and voltage is high enough, it will penetrate even dry skin.
So in short - if the object is neutral and insulating - no electrons jump. If the object is charged or is a conductor of electric current (especially direct current) - electrons might jump between the object and your finger.


OR


Only if it is more positively charged than we are. If the object has the same electric potential as we have, the electrons in the atoms closest to the surface will repel each other as they get too close, and that’s the force we feel when we “touch” something.

Answer 2

Answer:-

Electrons are very important in the world of electronics. The very small particles can stream through wires and circuits, creating currents of electricity. The electrons move from negatively charged parts to positively charged ones. ... When the electrons move, the current can flow through the system
