Interconnected System

Interconnected System The connection of many generating stations such as hydro power plant, Thermal power plant, Nuclear power plant etc running in parallel is called interconnected system. The interconnected system may be two types (i) Integrated and (ii) Uni-integrated. An integrated interconnection results in maximum overall economy. But most of the system interconnections are unintegrated. […]

Electric Cells

Electric Cell An Electric cell is source of electrical energy. The cell gives dc current. The emf developed and current supplied by a cell is very small. The electrical energy can be stored in cell. Definition of Electric Cell A cell is source of emf in which chemical energy is converted into electrical energy. Forming […]

Semiconductor Physics and Materials

Semiconductor Physics and Materials Semiconductor materials are those materials their conductivity lies in between the conductivity of conductors and insulators Germanium, Silicon, Carbon etc. are the semiconductor materials. Due to some useful properties of semiconductors they are extensively used in electronic circuits. Before the invention of semiconductors as an electronic components tube devices are used […]

Fuse and Types of Fuses

INTRODUCTION Electrical Fuse is simple and cheapest device which are used for interrupting an electrical circuit under abnormal conditions (such as short circuit conditions, overload conditions etc). Fuses are used upto 66kv called high voltage fuse and low voltage fuse upto 400V. In this article, we discuss about definition of fuse, working principle and fuse, […]
