Have you ever experienced a shock when you touch a metal door knob after walking across a carpet?​

Answer»

Answer:

We call this built-up electric charge "STATIC electricity." ... As you WALK over carpet in socks, your feet rub electrons off the carpet, leaving you with 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.
