Who is Nikola Tesla

Who is Nikola Tesla? Nikola Tesla was born on july 10th, 1856 in smiljan, in the austrian empire. He emigrated to the US in 1884 to work with Thomas Edison on his electrical systems, but their differing ideas and philosophies caused Tesla to leave after only a few months.

Electricity at the time had many problems. Direct Current, or DC, was used, and it was hard to step up or down to the right voltage. Power stations were required every mile, and power and voltage loss were high over long distances. Tesla’s solution to this is Alternating Current, or AC. Unlike DC, AC current alternates direction almost sixty times per second, or at a frequency of 60 hertz. Transformers are used to step the voltage up or down efficiently, and AC can travel greater distances at a higher voltage with minimal power loss. AC is what powers outlets and appliances, while DC is used for batteries and smaller devices.

Motors powered by DC current are used for smaller applications like robots and fans, but are very inefficient and wear out quickly at a large industrial scale. DC motors use brushes and mechanical switching to cause rotation, and the conductive brushes inside wear out quickly. Additionally, they are not suitable for the high voltages required in a factory setting. So, Tesla invented a new type of motor that ran on AC power, called the induction motor. It used polyphase AC, which is when multiple AC currents are combined, to ensure stable performance. Induction motors use a spinning magnetic field to turn the rotor, which means no brushes are needed. Induction motors are much more scalable and efficient and can handle higher voltages.

There are many myths about Nikola Tesla and his inventions, and separating fact from fiction can be a challenge.

Myth 1: Tesla was insane or mentally ill. There are a few reasons that many might think that, the first being Tesla was obsessed with the number three. He would walk around a building three times before entering, and set 18 napkins out on the table, because 18 is divisible by three. Tesla would also have nervous breakdowns from time to time, and became increasingly isolated to work on his experiments with electricity. His projects and habits at the time made people view him as a sort of mad scientist, and his views were not widely accepted. The reason for this myth is largely because of the culture of the time, and modern scientists have labeled much of the rest as symptoms of OCD, not insanity.

Myth 2: Tesla invented the electric car. Tesla did many experiments with electricity, but this was not one of them. Electric cars already existed before Tesla, and the electric car company Tesla motors has no connection to Nikola Tesla.

Myth 3: Tesla could hold spheres of electricity in his hands. You may have seen a picture like this before. In the picture he is using a Tesla coil to make balls of electricity hover over his palm. In reality, they are only small sparks that last for a microsecond, but by exposing the film more then once, they can make it appear that a cluster, or sphere, of those sparks is levitating over Tesla’s hand.

In conclusion, Nikola Tesla was not a mythical figure or a mad scientist, but a practical engineer who solved major problems in early electrical systems. His work on alternating current and the induction motor made efficient long-distance power transmission possible and helped shape modern industry. While many myths exaggerate his life and inventions, Tesla’s real legacy is found in electrical systems and technologies that are still used today.
