question 1 - 13
karen was walking across the carpet in her home wearing a pair of woolen socks on her feet. this caused a static charge to build up on her body. which of the following items
would most likely cause a spark or static discharge when karen touches it?
a wooden door
a plastic cup
a metal faucet
a cotton towel

Explanation:

Static discharge occurs when a charged object comes into contact with a conductor. A metal faucet is a good conductor. When Karen, who has a static charge on her body (from walking on the carpet and wearing woolen socks), touches the metal faucet (a conductor), electrons will flow rapidly, causing a spark or static discharge. A cotton towel is an insulator (does not conduct electricity well), a plastic cup is also an insulator, and a wooden door (wood is generally an insulator unless wet) would not cause a static discharge as easily as a metal (a conductor).

Answer:

B. A metal faucet
