Let's explore why electric fields cannot penetrate a closed conductor. This makes a closed conductor shield the inside from outside electric fields. They are useful in protecting sensitive electronic equipment's from stray fields. This effect was first studied by Michael Faraday, and hence closed conductors are often called Faraday cages.
