Dielectrics Any non-conducting or insulating medium between any two point charges keeps, the charges isolated. This type of medium is called dielectric medium. Examples of…

Capacitance of Capacitor Capacitance is the ability to store electrical energy. Almost all things, including you, can store some electrical energy and therefore have capacitance.…

‘Capacitor’ means ‘who can hold’. Normally the body which can hold charges is called capacitor. This is the main reason for its nomenclature. But the…

An insulator is substances that block or retard the flow of electrical or thermal currents. The particles of the insulator do not permit the free…

Conservation of charge If a glass rod is rubbed by a silk, then the glass rod becomes positively charged and the silk becomes negatively charged.…

Quantization of charge Quantization of charge means that when we say something has a given charge, we mean that that is how many times the…

Concept of Electric Dipole If two poles of same strength are placed very close to each other, it forms a magnetic dipole. Similarly, if two…

Explanation of Equipotential surface Any surface over which the potential is constant is called an equipotential surface. In other words, the potential difference between any…

Characteristics and Properties of an equipotential surface Any surface over which the potential is constant is called an equipotential surface. In other words, the potential…

Equipotential surface We have come to know that potential everywhere on earth’s surface is same (zero), as the surface of the earth is a good…
