Question

how can dc be produced by electric generator

Answer 1

Oil may be the world's favorite fuel, but not for much longer. Modern homes are powered mostly by electricity and it won't be long before most of us are driving electric cars as well. Electricity is superbly convenient. You can produce it in all kinds of different ways using everything from coal and oil to wind and waves. You can make it in one place and use it on the other side of the world if you want to. And, once you've produced it, you can store it in batteries and use it days, weeks, months, or even years later. What makes electric power possible—and indeed practical—is a superb electromagnetic device called an electricity generator: a kind of electric motor working in reverse that converts ordinary energy into electricity. Let's take a closer look at generators and find out how they work!
