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 conductor or semiconductor. As you know conductor is a material that allows the flow of electrons when an electric field… [Read More]
DC Circuits
DC Circuits are the basic building blocks of electronic projects. DC circuits may be power supply circuits, They also include electronic components like resistor, capacitor, diode, transistor etc. In this section you will learn DC circuit basics and DC electrical circuits used in electronics.
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 Law is also involved. A German physicist Georg Simon Ohm discovered the ohms law and found the relationship between current,… [Read More]
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 electrons. Whereas insulator is a material suitable for preventing the flow of electricity. They bypass or store charge and the… [Read More]

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 insulator and their electrical properties. Electronic devices and components are made up of conductor, semiconductor or insulator. The energy level… [Read More]
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 and metallic substances. The Atom is a tiny particle that can be divided further into a million parts having properties… [Read More]
Coulombs Law and Electric Charge in Electricity
According to physics terminology, electric charge experience force when kept in a magnetic field. Here electric charge is in the form of matter which may be the positive charge or negative charge. Positive charge is the composition of protons and negative charge contains electrons. When protons or electrons move in the electric field they produce electric… [Read More]
