That’s because metal is a great conductor of electricity. (In fact, so is the human body, which is why you can sometimes pass the shock on to someone else.) The opposite of a conductor is an insulator, which impedes the flow of electrons from one material to another. Rubber is a gr...

What's the strongest type of metal? Describe what the property of a substance is and give some examples. Describe what are the properties of matter? What property makes metal a good conductor and rubber a good insulator? What are four chemical and physical properties of elements?
The concept of the parallel plate capacitor is generally used as the starting point for explaining most practical capacitor constructions. It consists of two conductive electrodes positioned parallel to each other and separated by an insulator, usually one of several polymers, ceramic materials, metal ...
