Conventional Current vs. Electron Current
Electron current and conventional current are two types of notation we use to mention current flow in a circuit. These two notations are opposite to each other. We need a notation to do some calculations […]
What is Electric Current?
Electricity is a great gift science that has given to mankind. We use electricity almost all the time and it has been a part of our modern lifestyle. We can’t even imagine our lives without […]
Ohms Law – Heat and Power
Every electronic and electrical appliance in this world runs with power. When this happens, some energy is dissipated in the form of Heat. Whereas the Power is the flow of voltage and current in a […]
Ohms Law Basics – Voltage, Current and Resistance
In the previous tutorial, we had discussed the applications of current, voltage, and importance of Coulomb’s law in electricity. But, without ohms law the operation of an electric circuit becomes incomplete. To fulfill this, Ohms […]
Examples of Conductor and Insulator with Applications
There are many types of conductor and insulator used in electrical and electronic circuits. Substances covered with metal shields are the electrical conductors. In a conductor, electric current flows in the form of negatively charged […]
Conductor and Insulator
Electricity travels through different materials like copper. But have you ever thought how metals conduct electricity? Do all metals conduct electricity and why? In this tutorial, you will know the different types of conductor and […]
Atom, Nucleus and Electron
Atomic Structure Every object and matter in this world can be broken down into smaller particles (molecules) that are invisible to our naked eye. The matter is the composition of atoms that form the material […]
Electronics and Its Applications
Electronics is an applied form of science that deals with electrons. It handles electric circuits containing active elements, passive elements and other underlying techniques making it as an important part of engineering. The world is […]
Current and Voltage – Basic Electricity
Every electronic circuit works under two electrical quantities, current and voltage and it is not possible to detect voltage and current with our naked eye. This tutorial is for beginners who are new to electronics. […]
Active and Passive Elements
Electronic systems are built around analog and digital components. They comprise resistors, capacitors, diodes, inductor, operational amplifiers and transistors. These components are often called active and passive elements. Majority of the analog circuits consist passive […]
