1 Introduction The word system is derived from the Greek word "Systema" which means an or- ganized relationship among functioning units or components. System analysis is a structured approach to problem solving that breaks down a system into its compo- nent pieces to determine how these component work together by interacting with each other to achieve their purpose. Descartes emphasised that a problem under consideration should be divided into as many parts as possible and then examined

Experiment No: 2 Open circuit and short circuit tests on single phase transformer 1 Aim • To understand the basic working principle of a transformer. • To obtain the equivalent circuit parameters from OC and SC tests‚ and to estimate efficiency & regulation at various loads. 2 Theory The physical basis of the transformer is mutual induction between two circuits linked by a common magnetic field. Transformer is required to pass electrical energy from one circuit to another‚ via the medium

1 Memory Basics Memory is the workspace for the computers processor. It is a temporary storage area where the programs and data being operated on by the processor must reside. Memory storage is considered temporary because the data and programs will remain there only as long as the computer has electrical power or is not reset. Before being shut down or reset‚ any data that has been changed should be saved to a more permanent storage device of some type (usually a hard disk) so it can

Inside the Cabin The interior space has always been strength for Tata and the same holds true for Bolt. What has changed and for the better is the styling of this cabin. The dashboard design will look striking to anyone who is familiar with older Tata cars. With black coloured theme‚ chrome/brushed silver detailing and glossy black accents‚ the prime features do look elegant. Bolt variants do not have the two-tone dash of Zest but the design itself makes the cabin quite appealing. The knobs and

A form of media that revolutionized the way humans communicate was the radio. David Sarnoff is the best candidate for the man who put radio on the map. Although it may have not been his choosing‚ the sinking of the Titanic in 1916 put his name in the record books. For three days straight‚ the young Sarnoff decoded messages from the sinking ship from his office in New York (Wells 36). The Titanic broadcast was groundbreaking‚ because it showed and economically profitable way by which radio could be
