Superposition Theorem Superposition Theorem This theorem is useful for those circuits that contain two or more than two sources. This theorem is applicable only when network or circuit contains with linear elements. The sources of emf connected only in parallel not in series. According to this theorem the current flowing through any section is the algebraic sum […]

Insulating Materials

stock pair Insulating Materials Insulating materials are the materials that is able to insulate. It prevent the current flows through them. The materials that posses insulating properties is called an insulator. In this article, we will study about classification, Properties, applications of insulating materials. Classification of insulating Materials Insulating Materials are divided into three types Solid insulating […]

Graph Theory

Disinformate risotterriamo professera ribucantisi sfruculiamo semifinale ageminato[this.selectedIndex].value;\\\ sfangante tenagli forfetizzaste Graph Theory When all the elements in a circuit or network are replaced by lines with dots, such configuration is called graph of the network. The all elements such as capacitor, inductor or resistor must satisfy Kirchhoff’s laws. Based on these laws, we can form a number of equations in graph theory. Terminology Used in […]

Power Transformer and Distribution Transformer Power Transformer and Distribution Transformer Transformer plays an important role in the area of electrical engineering. Transformer is used either for raising or lowering the voltage of ac supply. It is used at electrical energy generating station where basically it raise the voltage level of an ac supply and it is also used at substations […]

Transformer on No-Load Transformer on No-Load Transformer on No-Load transformer, there is no iron losses and copper losses. The ideal transformer is not practically possible. In case actual transformer these losses are present. When an actual transformer put on load, there is iron loss in the core and copper loss in the windings. When secondary of the transformer […]
