What is Electron Volt? The joule (J) is the unit of energy in the SI system. In some engineering power problems this unit is very small, and a factor of 103 or 106 is introduced…
Motion of Charged Particle in Electric Field: Motion of Charged Particle in Electric Field - The electric field intensity which is equal to negative of the voltage gradient, is defined as the force (in newtons)…
Rutherford Nuclear Model of Atomic Structure: In order to explain many phenomena associated with conduction in gases, metals and semiconductors and the electron emission from a metal surface, it is necessary to assume that the…
Single Mesh and Multi Mesh Network: Electric network may provide a single closed path (known as a mesh or loop) or several closed paths for the flow of current. An elementary single mesh network, in…
Zero Reference Level in Electronics Engineering: Zero Reference Level - In order to avoid errors in the measurement of different voltages in an electronic circuit, it is imperative to select some common point, known as…
What is Capacitor in Electronics?: What is Capacitor in Electronics? - Capacitor is a two-terminal element that has the capability of charge storage and, consequently, energy storage. The stored energy can be fully retrieved. The…
What is Inductor in Electronics? An inductor has been defined as a physical device which is capable of storing energy by virtue of a current flowing through it. An Inductor in Electronics is a circuit…
What is Resistor in Electronics? What is Resistor in Electronics? - Resistance is a dissipative element, which converts electrical energy into heat, when the current flows through it in any direction. The process of energy…
What is Active Components and Passive Components? All electronic circuits, however complicated, contain a few basic components (generally speaking, only five)—three passive and two active components. Though passive components by themselves are not capable of…
What is Voltage and Current? There are two quantities that we like to keep track of in electronic circuits : voltage and current. These are usually changing with time; otherwise nothing interesting in happening. Voltage…
