1 00:00:00,000 --> 00:00:07,000 Whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa. 2 00:00:07,000 --> 00:00:10,800 And now, the history of electricity. 3 00:00:10,800 --> 00:00:13,500 Here's Dr. Textbook. 4 00:00:13,500 --> 00:00:15,500 Hello. 5 00:00:15,500 --> 00:00:19,500 Maybe you think that one or two people discovered electricity. 6 00:00:19,500 --> 00:00:23,000 Well actually, electricity is all around us, it occurs in nature. 7 00:00:23,000 --> 00:00:25,500 Oh, ah! 8 00:00:25,500 --> 00:00:27,500 Very funny. 9 00:00:27,500 --> 00:00:29,500 An electric buzzer. 10 00:00:29,500 --> 00:00:33,500 Now, you probably heard some story about Ben Franklin flying his kite. 11 00:00:33,500 --> 00:00:40,500 Well, don't believe for one second that Mr. Franklin was standing out in a wet field with lightning raging about him, holding on to a brass key. 12 00:00:40,500 --> 00:00:50,500 No, he actually was standing in the distance, observing the kite, taking notes, and what he found out was that lightning is actually an electrical spark. 13 00:00:50,500 --> 00:00:53,500 Now, on to Alessandro Volta. 14 00:00:53,500 --> 00:01:02,500 Mr. Volta was the first man to build a battery, and he did this by taking small plates of copper and zinc and putting moist pieces of paper in between it. 15 00:01:02,500 --> 00:01:10,500 So, as an ode to Volta, I will take this nine-volt battery and stick it on my moist tongue. 16 00:01:10,500 --> 00:01:13,500 Not a very good idea. 17 00:01:14,500 --> 00:01:18,500 Thomas Edison built a generator to make electrical current. 18 00:01:18,500 --> 00:01:27,500 But it actually was a man called Nikola Tesla who found out that by alternating the electrons in an electrical circuit was a better way to produce electricity. 19 00:01:27,500 --> 00:01:30,500 And this we call alternating current. 20 00:01:30,500 --> 00:01:33,500 And the first place this occurred was in Niagara Falls. 21 00:01:33,500 --> 00:01:37,500 Wait! There's more to learn! 22 00:01:37,500 --> 00:01:41,500 This has been the History of Electricity.
