This Article explains the how the DC generator works, and constructional details of DC generator.              DC generator is a Machine which converts  mechanical energy into electrical energy. Rotating prime movers help to move the armature conductor in the stationary magnetic field, so that the conductor cuts the magnetic field, an e.m.f induced in the conductor ( according to faradays law ).      If induced e.m.f  collected by brush and slip ring the e.m.f is forming the sine wave (AC, i.e +ve and -ve values) due changing value of cutting the flux in different positions of the conductor. simple ac generator, image source: Wikipedia When it right angle to field, emf is zeo (at 0°,180°,360°), But when it align with magnetic field e.m.f values are maximum(at 90°,270°). in between these positions, the e.m.f values are in between zero and maximum, positive (between 0° to 90°, between 90°to180°) and negative (between 180° to...

  This article from I saiah 42. May the Lord bless through his word. Even though God has chosen Israel as his people, He is the God of the entire world. He has the plan for salvation and blessing for the entire world. God has chosen and called Abraham, But he promised that, you will be a blessing, All peoples on earth will be blessed through you.   In Isaiah chapter 42, God is saying that " I will put my spirit on my servant, he will do justice for the gentiles. It means the God of justice, express his compassion, anger on injustice here. Some of his servants were blind, not given attention to the injustice. So God's word here about his servant with whom God's spirit stayed on..(42:2-4) "He will not shout or cry out, or raise his voice in the streets. A bruised reed he will not break, and a smoldering wick he will not snuff out. In faithfulness he will bring forth justice; he will not falter or be discouraged till he establishes justice on earth. In his teaching the ...

  This article share the word of God from Isaiah 41. (Israel the God's people went away from Lord, punished by him. And he is the one who rise leader (Cyrus) and bring back the people. These are words by God to Isaiah long before it going to happen) Listen, be silent before me. Who rise up the righteous from east by calling him to God's Service? Who gave victory to this man over many nations? He reduce the army to dust, he scatter them like chaff with his bow. Who made this man to walk safely in unfamiliar grounds? Who has done such mighty deeds, summoning each new generation from the beginning? It is I,  the Lord, the First and Last, I am alone He. Israel,  My servant,  Jacob, my chosen one,  Descended from Abraham my friend. I have called you back from the ends of the earth,  You are My servant, For I have chosen you, and will not throw you away. Don't be afraid, for I am with you. Don't be discouraged, for I am your God. I will strengthen you and help yo...

      ..T his series going to take you to the paul through his letter. God will strengthen you from his word... Dear Timothy, My son !

We are not worthy of it. Because of his plan which he had before the world beginning, we are ...

      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...
