In the previous article, we discussed Ohm’s Law of current electricity. In this article, we’re going to perform an experiment for the verification of Ohm’s law. This practical verification of Ohm’s law is very important for the students of grades 10 and 12. This is a lab-based experiment to verify Ohm’s law or Ohm’s law … Read more
A current-carrying wire placed in an external magnetic field experiences a magnetic force. This is similar to the force between two magnets. Because a current-carrying conductor behaves like a magnet. Also, It will show the same interactions as other magnets when it is placed in front of a magnet. Even if we place two current-carrying … Read more
Logic gates are the basic building blocks of digital electronics that follow different logical operations. These gates have significant roles in the construction of logical circuits for different computations. Digital electronic devices contain integrated circuits (ICs) which are made of logical gates. In this article, we’re going to explore basic logic gates with truth tables, … Read more
We have discussed almost everything on electric charges in another article (link is given in the related posts section at below). In this article, we are going to discuss the basic properties of an electric charge. This will be helpful for the students of class 10 and class 12. Contents in this article: What is … Read more
Earlier we have discussed the Electric field and Electric field lines. Similar to the electric field lines, there exist magnetic field lines in a Magnetic field. In this article, we are going to discuss the definition and the properties of Magnetic field lines and the diagram of magnetic field lines for a bar magnet, solenoid, … Read more
If we bring a bar magnet near another bar magnet then a force acts between the magnets. Same poles of magnets repel and opposite poles attract each other. This interaction is very similar to electric charges, but not exactly. Now question is, what makes this to happen? The answer is the magnetic force in magnetic … Read more
Scientist Hans Christian Oersted first observed the deflection of a magnetic needle or compass placed near a current-carrying wire. This concludes that a current-carrying wire can produce a magnetic field around it. In another article, we have discussed the Origin, definition, unit and dimension of magnetic field. Since the magnetic field is a vector quantity, … Read more
A static charge produces an electric field around it. Again, when a charge is in motion, it produces a magnetic field around it. But how electromagnetic waves are produced? An accelerating charge produces electromagnetic waves where both the electric field and magnetic field propagate together in an electromagnetic field. Electromagnetic waves are nothing but the … Read more
In the first four articles on electrostatics, we learned about electric charges, electric charge distributions, electric field and Coulomb’s law of electric force. We became to know that the charges of the same sign will go away and opposite charges will come closer due to electrostatic interactions. The paths through which the charges move due … Read more
In the first two articles on Electrostatics, we learned about electric charges and their distributions on a Conductor. We became to know that a static electric charge produces an electric field and a moving charge produces a magnetic field around it. Electric charges can move due to electrostatic force and this force comes from the … Read more
