Physics Edupedia: Learn with fun

  Physics is a core STEM subject that is also one of the most feared due to its extensive syllabus and complex concepts. Physics is not a subject that can be learned overnight, but it is a subject that can be learned with hard work and dedication. Many students are afraid of physics because it contains many complex definitions, laws, theories, and derivations, as well as numerical based on all the concepts. Physics is not an easy subject, and you will need to put in a lot of effort to succeed. Fear not! With some good techniques, you should be able to ace physics even in the toughest exams like JEE and NEET. Here are some Do’s and Don'ts to follow as you study for your physics exam , which will help you in tackling it with ease. Do’s 1.      Make your basics strong The only way to learn any subject is to understand the fundamental ideas and have a deep interest in learning them. Physics is a subject with many complex ideas and a wide range of practical applic...

  You've probably noticed various electrical circuits and boards around you. Those circuits contain numerous components. Have you ever wondered what these components are called or what their applications are? These components are known as 'resistors' and are found in almost all electrical equipment. They have varying values based on the colour of their bands. Each resistor has a fixed resistance value. Now the question is, what exactly is resistance ? The origin of resistance can be traced back to the well-known electrical circuit law known as Ohm's law . According to Ohm's law , the current flowing through a conductor between two points is proportional to the voltage across the two points. Using the proportionality constant - the resistance , the current through the conductor is given as where is the ' V' voltage measured across the conductor and 'R'   is the resistance of the conductor. Georg Simon Ohm discovered the famous Ohm's law in 1...
