GEOLOGY

Detailed explanation-1: -As your feet rub against the carpet, your body either steals or abandons electrons (depending on what you’re wearing on your feet). So when you reach for the doorknob, millions of extra electrons leap from you to the knob (or from the door knob to you), giving you a shock.

Detailed explanation-2: -Electric charges are carried by electrons. When we shuffle our feet on the carpet, we are rubbing electrons off the carpet and onto our body. When we then touch a metal doorknob, for example, the extra electrons jump from our body to the metal, making a spark.

Detailed explanation-3: -When you touch a doorknob (or something else made of metal), which has a positive charge with few electrons, the extra electrons want to jump from you to the knob. That tiny shock you feel is a result of the quick movement of these electrons.

Detailed explanation-4: -There is static electricity on our hand from rubbing the wool, which then discharges when we touch the conducting doorknob, causing us to register a shock with the nerves in our hands. This discharge is called static discharge.

Detailed explanation-5: -In static electricity, electrons are moved around mechanically (i.e. by someone rubbing two things together). When you drag your feet across the carpet, extra charge is scraped off the rug and collects on your body. When you touch a doorknob, all the charge wants to leave you and go to the doorknob.
