Question

Plastic wrap becomes electrically charged when pulled from its box. As a result, it is attracted to objects such as food containers. Does the wrap stick better to plastic containers or to metal containers? Discuss.

Answer 1

Explanation:

It sticks better to the plastic containers. We know that plastic is one among the good insulator, Hence as soon as the charged plastic wrap makes contact with the box, the charges will remain relatively fixed in particular location. Which will subsequently maintain the electrical attraction. When charged plastic wrap comes in contact with the metal, on the other hand, the charged plastic wrap will discharge through the metal since metal is a good conductor, causing it to lose its electrical properties.
