Tesla Coils




Hello there! This time my blog will discuss about Tesla Coils, its origin and how they work in the first place.

Tesla Coil was invented by Nikola Tesla in 1891 – that’s why the device has his name, and was shown in a presentation by him. Scientists were amazed by this eye-opener invention.


Nikola got the idea from an 1826 invention that could amplify electricity via a wire current. He improved this idea and magnified it as to have the complete setup for a modern amplifier. To this day, it is used as an alternative for an amplifier. However, now there are other electric amplifiers that may be more effective.

The Tesla Coil is very famous for being able to easily discharge massive amounts of electricity in a short amount of time. The device has the ability to reach discharges of several million volts. Many scientists use this coil to release electricity into the air for experiments, entertainment, museum exhibitions, and special effects. Some even create a mini Tesla Coil that usually discharges 9 – 60 volts.

In scientific terms, the Tesla Coil is a radio frequency oscillator that drives a double-tuned resonant transformer to produce high voltages with low currents. In more simple terms, it’s an electric coil that uses a curled wire and a rod to generate electricity.

By coiling around, it creates a sort of double current that will only flow through the wire. When it finishes charging up it will travel to the ball on the top and discharge a large amount of electricity. There are also larger Tesla coils that use external tools to generate even more currents. The latter are used mainly for large structures, experiments, or just to show off.

Please note that Tesla Coils are potentially dangerous devices and precautions must be taken before every operation to prevent possible damage to property, living thing, or even death. Unqualified personnel must never be allowed to operate the Tesla Coil. 

Thanks for reading! -Nat

Vectors and Scalars

I want to talk about Vectors and Scalars . This is about physics. Now you might be asking, what is a vector? Vectors have a magnitude and direction. In case you don’t know, magnitude is the size of the movement, but it’s not distance. Since it’s a vector quantity, it’s called displacement .  For example, the displacement of a leaf being blown by the wind is 50 centimeters to the east. This is a vector quantity because it has a magnitude (50 cm) and a direction (east). And there’s more...  If someone asks you the version of speed in a vector quantity, it’s called velocity .  For example, the velocity of a ball being thrown is 5m/s to the east. In other words, five meters per second to the east.  You can find the displacement as long as you have the velocity and time. Multiply them and you will get the displacement. If the velocity is 5m/s and the time is 10 seconds, you need to multiply them ( 5 x 10 ) to get the displacement, which is 50 meters.  A...

Cheryl's Birthday Problem (from SASMO 2015) and Solution

Image
Hello! Nat here, and in this blog, I am going to discuss and give the solution to the famous Cheryl birthday problem. This was popular because it is a difficult logic puzzle and involving the ability of carefully tracking down hints in the conversation and working with only a small amount of data. Here’s the question: Albert and Bernard just became friends with Cheryl, and they want to know when her birthday is. Cheryl gives them a list of 10 possible dates. May 15           May 16           May 19 June 17          June 18 July 14           July 16 August 14       August 15       August 17 Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively. Albert: I don’t know when Cheryl’s birthday is, but I know that Bernard doesn’t know too. Bernard: At first I don’t know whe...

Black Holes

Image
Black Holes are holes in space that absorbs anything in their way, even stars. They are made by a star exploding as supernova and the star must be about 3 times the mass of the sun. This is called the Oppenheimer-Volkoff limit.  Its core will collapse into a neutron star, but its gravity is so strong that it starts sucking in material from outer space and later turns into a black hole.  Once they absorb enough matter to become powerful and massive, they can start creating galaxies. That is why black holes can be found in the heart of galaxies.  Sometimes, black holes will emit the brightest light waves in the universe – quasars.  Now you might be asking, why don’t we see like “blink, blink” from earth? The answer is that they are very far. The furthest quasar from us is about 14 billion light years away. However, we are lucky to be on a planet that isn’t near a black hole. If we were near a black hole, we would get our atmosphere stripped first then ...
