What is Secondary Emission? When a beam of high velocity electrons suddenly strikes a metallic surface, they give up their kinetic energy to electrons and atoms which they strike. Some…
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…
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…
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…
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…
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…
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…
