Introduction Capacitor is a device which stores electrical energy. Capacitor is a system of two-conductors which carries charges of opposite sign but of equal magnitudes and separated by an insulating medium. The insulating area is either an electric insulator or vacuum like glass, paper, air, semiconductor or dielectric. Uses of Capacitor Capacitors are used for […]
Parallel plate capacitors are capacitors with electrodes and insulating material which are arranged in a parallel (dielectric) pattern. The electrodes are two conductive plates. In between there is a dielectric. For plates, this acts as a divider. Parallel Plate The two plates of the parallel plate capacitor are similar in size. They are connected to

Capacitance and capacitors, Class 12, Electrostatics, IIT JEE, PhysicsCapacitance is a property of an electric conductor or group of conductors determined by the number of separated electric charges carried in it per unit change of electrical potential. Capacitance involves the storing of electrical energy as well. When an electric charge is passed between two originally inert wires, both become evenly charged, one positively
Calculation of capacitance is a very simple formula. Before entering the calculation, it is important to understand the concept of calculation of capacitance. The calculation of capacitance means determining the capacitance by charge stored in the capacitor and its electric potential. Also, it is measured in farads. How is the Calculation of Capacitance Performed?

Capacitance and capacitors, Class 12, Electrostatics, IIT JEE, PhysicsBubbles and Capillary rise Introduction: Surface tension is the energy or work required to raise the surface area of a liquid due to intermolecular forces. Because the liquid composition (e.g., water vs gasoline) and the solutes in the liquid (e.g., surfactants like detergent) influence these intermolecular pressures, each solution has different surface tension features. Surface

Capacitance and capacitors, Class 12, Electrostatics, IIT JEE, PhysicsIn this material, let us know the history of capacitors. In the month of October in 1745, German Ewald Georg von Kleist of Pomerania noticed that charge can be collected in a specific amount of water in a handheld glass jar connected to a high-voltage electrostatic generator with the help of a wire. Von Kleist
Dielectrics, as a general rule, can be portrayed as materials that are extremely helpless conveyors of electric flow. They are essentially protectors and contain no free electrons. Dielectrics can be effortlessly spellbound when an electric field is applied to them. Along these lines, their conduct in an electric field is altogether unique in relation to

Capacitance and capacitors, Class 12, Electrostatics, IIT JEE, PhysicsGauss law is one of the fundamentals of physics. It is regarding the production of electric fields by the distribution of charges over the region. Gauss’s law states that the flux coming out of the surface equals 1 /ϵ0 of the charge enclosed by the surface. Gauss theorem has various applications. In this study material

Class 12, Electrostatics, Gauss’s theorem, IIT JEE, PhysicsCommon Emitter Amplifier Transistor amplifiers boost AC input signals that alternate between positive and negative values. The transistor must then be able to function between these two maximum or peak values, so some method of presenting the amplifier’s circuit layout is required. Biasing is a technique for accomplishing this. Biasing is essential in amplifier design

Class 12, Electrostatics, Gauss’s theorem, IIT JEE, PhysicsIt is a fact that a static electric field encloses a positive or negative charge and that a flow of energy tube or flux exists inside that static electric field. The electric charge radiates or emanates this flux. The magnitude of this flux flow is determined by the amount of charge emitted. The Gauss theorem
