We already know that the Ohm’s law is a fundamental law in current electricity. But, Scientist Kirchhoff has given another two fundamental rules of electricity. With the help of these two rules one can easily find the current, voltage and resistance in an electrical circuit by using nodal analysis and loop analysis methods. In this … Read more
There are two basic laws of current electricity – one is Ohm’s law and another one is Kirchhoff’s law. Ohm’s law of current electricity gives the simplest relation between the electric current and voltage across a resistance. Kirchhoff’s laws tell us how to calculate electric current and voltage at a junction point or in a … Read more
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
An electrical circuit consists of some electrical components and a source of voltage or current. These circuit components perform all the activities in a circuit. We need to know the function of every circuit component to use these properly in a circuit. Examples of some electrical components are resistors, capacitors, inductors, diodes, transistors etc. In … Read more
