If a body has an unequal number of protons and electrons then we call it a charged body. It can have either positive charges or negative charges. Either type of charge can produce an electric field near it. The amount of charges and the shape of the body determine the type and value of the … Read more
If we bring two electric charges close to each other, they exert a force on each other. This force is known as the electrostatic or electric force. It is a natural property of electric charges. Every electric charge or charged body exerts an electric force on another charged body near it. In this article, I’m … Read more
Electrostatics Article – 7 Let a source charge Q produces an electric field E and a positive test charge q is placed at a distance r from the source charge. Coulomb’s law gives the expression for the electrostatic force on the positive charge q due to the source charge Q. Now, if we want to … Read more
All bodies are neutral in nature. Charged bodies are created either artificially or by natural phenomena like lightning. There are three processes to charge a body artificially – Friction, Induction and Conduction. In this article, we will learn how to produce electric charge by induction process. Here, I am going to explain how can two … Read more
A continuously charged conductor can have three types of charge densities. We already discussed surface charge density and volume charge density in other two articles. In this article, we’re going to discuss line charge density. Here you will learn the concept, definition and formula of linear charge density and how to calculate it. Contents in … Read more
A three-dimensional conductor can have three types of charge distributions. These are Line charge distribution, surface charge distribution and volume charge distribution. Obviously, there will be three types of charge densities for these three distributions. In the other two articles, we have discussed the Linear charge density and surface charge density of different conductors. In … Read more
A Capacitor is an important component in an electrical circuit. We have discussed different types of capacitors in other articles. Like other components (resistors, inductors), a capacitor also offers opposition to the current flow (Direct current only) through it. That means it generates impedance. Ohm’s law tells us that an impedance causes a voltage drop. … Read more
In this article, we are going to discuss MCQ questions on electric potential for class 12. These multiple choice questions on electrostatic potential will be helpful for class 12 students of CBSE board and all other boards. Chapter-2: Electrostatic potential and Capacitance MCQ on electric potential 1. If V be the electric potential at the … Read more
We have already learned electric charges and electric field in detail. Now, it’s time to practice some multiple-choice questions on electric charges and electric fields for class 12 physics. It is very helpful for board exams and NEET exam. This topic is included in class 12 NCERT physics chapter 1 for CBSE and other boards. … 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
