Basics for Electrical Engineers.
Without knowing the fundamentals, Laws, principle behind the concepts study become hard, makes more difficult the learning process. Some of the basic rules and concepts are important to understand the electrical machines. Most of the electrical machine's principles running around the electromagnetic induction concepts. Initially the DC source invented using battery using coins, chemicals. till the invention Alternating current (AC). In 1931 Michael faraday found that the flux changing causing the induction of e.m.f i.e. electro motive force. But now-a- days maximum we are using the AC, with the desired voltage with the help of transformer. it is good to know the laws and principles behind this which are helping silently. Faraday's Experiment: Consider a coil C of several turns connected to a central zero galvanometer. If a permanent magnet is moved towards the coil it will be observed that the galvanometer shows deflection in one direction...
