Science > Physics > Electrostatics > Introduction to Static Electricity Electricity is a very important form of energy which can be easily converted into other forms of energy. Electricity can be produced at one place and can be transmitted to long distances. Electricity is a branch of Physics which deals with charges, stationary and moving. […]
Science > Physics > Electrostatics > Quantization of Electric Charge In this article, we shall study the concept of quantization of electric charge and the principle of conservation of electric charges. The fact that all observable charges are always some integral multiple of elementary charge e = 1.6 × 10-19 C is known as quantization […]
Science > Physics > Electrostatics > Charging a Body and Detection of Charge In this article, we shall study methods of charging of body and different apparatus used for detection of charge on the body. Charging of Body: Charging by Friction: When a body is rubbed to another, there is a transfer of electrons from […]
Science > Chemistry > Solid State > Semiconductors On the basis of electrical conductivity, substances can be classified into three types conductors, insulators, and semiconductors. In this article, we shall have a brief idea of semiconductors. Semiconductors are the substances whose conductivity lies between the conductors and insulators e.g. Germanium, Silicon, etc. They are covalent solids. […]
Science > Chemistry > Solid State > Electrical Properties of Solids In the last article, we have studied the dielectric properties of solids. In this article, we shall study the electrical properties of solids. Electrical Conductivity: The electrical conductivity of solids is due to the motion of electron or positive holes. The conductivity due to the motion […]
Science > Physics > Introduction to Physics List of Sub-Topics: 1.1.1.1 What is Physics? Science word is derived from the Latin word ‘Scientia’ which means ‘to know’. Science has many disciplines, Physics being one of them. The word Physics is derived from the Greek word ‘Fusis’ meaning ‘nature’. Physics is that branch of Science which […]
