Electric current

a) According to the right-hand rule, the direction of the magnetic fields of the 3 wires are shown: We find the magnetic fields B1, B2 and B3: 퐵1=퐵2= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟒퟐ.ퟔퟔퟎ풖푻 2휋푟 2휋( 2푎) 2 ∗ 3.14 ∗( 2(0.0121)) 퐵3= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟐퟎ.ퟏퟏퟎ풖푻 2휋푟 2휋(3푎) 2 ∗ 3.14 ∗(3∗(0.0121)) The x components of the B1 and B2 cancel each other; therefore the net magnetic field will be downward and we have (the negative sign is because the direction is downward): 퐵=− 퐵1cos 45 +…

“I don’t care that they stole my idea, I care that they don’t have any of their own” (Tesla). Those words and many more were uttered from the great master mind that is Nikola Tesla. Born in 1856, the Serbian-American resident of the town of Smiljan, which is in present day Croatia, was set on track for greatness. His father, a humble priest, however, his mother had a crafty hand for household tools and mechanical appliances which may have played a great influence on Tesla’s future creative…

redesigning the direct current generators that ran Edison’s business. Then Edison offered Tesla $50,000 for the new improvements on the generators. After Tesla’s work was done, Edison claimed that he wasn’t serious about the offer for the new generator. So then Tesla moved on to team up with George Westinghouse to commercialize the new invention of alternating currents. This was a strong competition with Thomas Edison’s direct currents and Westinghouse’s alternating currents.…

parting ways with Edison, in 1885 Tesla received funding for the Tesla Electric Light Company and was tasked by his investors to develop improved arc lighting. After successfully doing so, however, Tesla was forced out of the venture and for a time had to work as a manual laborer in order to survive. His luck changed in 1887, when he was able to find interest in his AC electrical system and funding for his new Tesla Electric Company. Setting straight to work, by the end of the year, Tesla had…

In 1892 Tesla and Westinghouse found themselves in a fierce battle with the newly formed General Electric Company, in an effort to cut costs and keep his company from going under, Westinghouse convinced Tesla to forgive all past and future royalties that Tesla might have been owed. While times were good the money that Tesla might have earned didn’t seem…

operator key down to complete the electric circuit of the battery,” (History). This action of pushing the operator key down sent electric signals across a wire to a receiver on the other end. Every system needed a key, a battery, wire and a line of poles between stations for the receiver. Charles Wheatstone and his peer developed a telegraph system with “five magnetic needles that could be pointed around a panel of letters and numbers by using an electric current,”…

Nikola Tesla "The spread of civilization may be likened to a fire; first a feeble spark, next a flickering flame, then a mighty blaze, ever-increasing in speed and power." Nikola Tesla is considered the father of the electric age. From the alternating current to neon signs, his inventions revolutionized the world. He had over 250 patents throughout the world. Nikola Tesla was born in Smiljan, Croatia on July 10th , 1856. He was born to Milutin Tesla and Đuka Mandic. His father was a Serbian…

telegraph operator from when he was 15 until he was 22. After his career in telegraphy, Edison moved on to being an inventor and entrepreneurial businessman. Thomas Edison’s inventions have had major impacts on society around the world. He invented the electric lightbulb, the phonograph, and the motion picture…

Nikola Tesla and The War Of Currents When you are watching a movie and it gets just a little too loud it only takes a click of a button to fix that, and when you want to remember a moment forever all it takes is a little raise of a camera and a click. Nikola accomplished many great things in his lifetime. Simple things that make life easier are often overlooked, but we have Nikola Tesla to thank for many; Tesla developed the alternating-current electrical system that is widely used today.…

Nikola Tesla was a man of wisdom. The war he had with Thomas edison went on for a long time. Nikola tesla invented the ac, a type of current we still use today. The whole war was over eddison and is dc current. Which means direct current. Tesla was born on July 10, 1856 in Smiljan, Croatia. He was not an american citizen at first. He came from the austrian empire to america. From 1856 to 1867 he was apart of the empire. Then he came to america and became a citizen here. His father was a priest…
