Albert Einstein won the Nobel Prize in 1905 for his explanation of Photoelectric effect. There were some failures of classical mechanics to explain this phenomenon. Then Einstein explained it on the basis of quantum theory. In this article, we are going to explore the definition and properties of Photoelectric effect explained by Einstein and will … Read more
Most of the materials are affected by the magnetic field. These materials are magnetic materials. These materials can show magnetic properties. The origin of magnetic moment in these materials is the rotation of orbital electrons around the nucleus. On the basis of the magnetic properties of materials, there are five types of magnetic materials – … Read more
The origin of magnetism is the motion of charged particles. In every atom, there are some electrons and protons. As the electrons are revolving around the nucleus and also spinning around their own axes, the atomic system behaves like a magnetic dipole. Therefore, atoms can produce a magnetic field or can have a magnetic moment … Read more
Nuclear fission and nuclear fusion are two nuclear phenomena to produce nuclear heat energy. But these two phenomena occur in different conditions and the amount of heat generation is also different in these two phenomena. In this article, we are going to discuss the definition, properties, examples, uses and differences between nuclear fission and nuclear … Read more
In recent exam pattern of class 8, 10 and 12, MCQ and short questions carry majority marks. In this context multiple choice questions are very much important to secure a good score in exams. Students need to find MCQs from the textbooks. But most of the students fail to gather majority of inside questions. Therefore, … Read more
A capacitor can store electric charges and releases them whenever it is required. But how can a capacitor store energy in it? What is the formula of energy stored in a capacitor? The application of an external voltage across a capacitor produces an electric field between the plates of the capacitor. This electric field moves … Read more
In the previous article, I explained the capacitance of different types of capacitors. A parallel plate capacitor is one of the most popular capacitors and it has wide applications in electrical circuits. In this article, I’m going to explore the capacitance of a parallel plate capacitor and its behavior in presence of a dielectric medium … Read more
A Capacitor is one of the most useful circuit components. A capacitor can store electric charge or electric energy in it. The capacitor is nothing but a conductor or the combination of two conductors having equal and opposite charges. Then what makes the capacitor different from a conductor? What are the different types of capacitors? … Read more
Electrostatics Lecture – 6: In the third article on electrostatics, we became to know that an electric charge can produce an electric field around it. Then we studied its properties and other things related to it. Since there are various types of charge distribution in different conductors, the formula for the electric field will be … Read more
In other articles, we became to know that an electric charge can produce an electric field around it and one can use Gauss’s law to find the electric fields due to charged conductors. This electric field is responsible for the electrostatic force between the charges. As a result, charged particles move in the electric field … Read more
