How many times do we use the switch in a day? Ever count them? Have you ever followed the wire back to the source, in your mind, and paused in wonderment at the true power you have at your fingertips? How many miles of electrical cable will your mind travel along before it reaches the 500-megawatt turbine generators at the power station? Now think about what life would be like without electricity. Actually, we do not have to go too far back in time to relive that scenario. Every device that uses electricity has been developed within the past one hundred years. We are now so dependent on electricity and the switch that it would be inconceivable to be without them. Some of us will remember when there were no electric lights in our homes, and gaslight and candles provided illumination. To others, such an existence will be beyond comprehension. The electricity that feeds the homes of developed countries is synonymous with shelter and has become as basic a staple as food and clothing. How did we come so far so fast?Modern electrical power distribution technology is largely the fruit of the labors of two men—Thomas Edison and Nikola Tesla.
