Principle of capacitor

Principle of capacitor The principle to increase the capacity of a capacitor is to place an uncharged and earthed metal plate nearer to a charged metallic plate. Then due to induction, the potential on the charged plate decreases. Explanation : A parallel plate capacitor consists of two metallic plates say A and B. Let a positive charge q is given

Beryllium behaviour

behaviour of Beryllium The first element shows some differences from the properties of the other elements in the group. Beryllium differs from the other alkaline earth metals because of its small size and high electronegativity. Beryllium differs from the other elements in the following aspects. Beryllium compounds are predominantly covalent due to its high polarizing power and its salts are

Types of capacitors

Capacitor is a device used to store an electric charge. There are three types of capacitors. Paper plate capacitor Electrolyte capacitor Mica capacitor (or) Multiple capacitor Paper plate capacitor : A paper plate capacitor consists of two thin metal foils made with tin. Generally, a paper soaked in wax is placed in between the metal foils and it is rolled
