Why do you get an electic shock if you touch a doorknob after walking across a carpet?

Answer 1

You get an electric shock if you touch a doorknob after walking on carpet because of built up of extra electrons transferred from the carpet to your feet and then body. The electrons stay built up on you until you touch something that they can discharge on, in this case a doorknob.

Answer 2

When you rub your feet on the carpet, your feet pick up electrons from the carpet. now you have negative, or unbalanced, charge. When you touch the door knob, the extra electrons jump to the doorknob. That is static electricity

Answer 3

When you walk over the carpet in socks, your feet rub electrons off the carpet, this gives you a slightly negative static charge. When you reach for a doorknob, you get a shock as electrons jump from you to the knob, which conducts electricity.

Answer 4

Static electricity that is built up as you walk across the carpet and is discharged as you touch the metal door knob

Answer 5

When you walk across the carpet you pick up stray electrons. Those electrons then transfer from you to the doorknob when you touch it causing a shock.

Answer 6

You build up a static electric charge as you walk. Touching a doorknob lets the charge leave your body thru the fingertip, where you have lots of nerve endings, so you feel this as a shock.
