Ques-1: What is a transformer and how does it work? Ans: A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. A transformer has no moving parts and is a completely static solid state device‚ which insures‚ under normal operating conditions‚ a long and trouble-free life. Construction of transformer is very simple‚ two or more coils of insulated

The City of Cebu (Cebuano: Dakbayan sa Sugbo‚ Filipino: Lungsod ng Cebu‚ Spanish: Ciudad de Cebú) is the capital city of the province of Cebu and is the "second city" of the Philippines‚ being the center of Metro Cebu‚ the second most populous Metropolitan area in the Philippines after Metro Manila. With a population of 866‚171 as per the 2010 census‚ it is the fifth most populated city in the country.[2] Cebu City is a significant center of commerce‚ trade and education in the Visayas area. The

For a given exercise‚ the system generates a report summarizing the results of each form of analysis and the way in which it contributes to the final grade. Experiences to date are encouraging‚ the system offering much faster and more comprehensive marking than

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

TRANSFORMER PROJECT You can make a transformer from magnet wire and an iron rod. Remember that magnet wire‚ although it looks bare‚ actually has an enamel coating on the outside that serves as insulation. Enamel is used on magnet wire so that the insulation is very thin and the coil of wire can be compacted into a smaller space‚ thus enhancing the inductive phenomenon. small gauge wire and cause it to melt‚ which is a very good example of how a fuse works‚ but could cause you to

A transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is very basic definition of transformer. History of Transformer The History of transformer commenced in the year of 1880. In the year of 1950 400KV electrical power transformer first introduced in high voltage electrical power system. In the early 1970s unit rating as large as 1100MVA were produced and 800KV and even higher KV class transformers were manufactured in year

The Transformers Transformers is a live action movie released by DreamWorks in 2007. The story follows the Transformers’ arrival on modern-day Earth and their interactions with the human race‚ as they search for the life-giving AllSpark and continue their ages-old civil war. The movie is fiction but also distinct in its own right. My favorite "Transformers" character is Bumblebee who is a robot that transforms into Sam’s car. I like him because he is a loyal Transformer and transforms into a Camaro
