Question

type your response in the box. imagine that someone is walking across a carpeted room and then touches a metal doorknob. describe what happens when a doorknob is touched if theres a buildup of static electricity.

Explanation:

When a person walks across a carpeted room, friction between their shoes and the carpet causes electrons to be transferred, building up static - electricity on their body. When they touch a metal doorknob, which is a good conductor, the static charge on their body quickly discharges through the doorknob. This results in an electric shock or a small spark as the excess electrons flow from the person to the metal object to equalize the electrical potential.

Answer:

A static - electricity discharge occurs, often felt as a small shock or seen as a spark, as the excess charge on the person's body is transferred to the metal doorknob.
