Need & Purpose of the Transistor
Before transistor we used tubes and electromagnetically switches to complete electrical circuits. But the problem was that they needed to be heated up first in order to work and sometimes you risked the possibility of them overheating. So we really needed something small and compact to replace those big and bulky circuitry and used too much energy to run.
It’s really simple and really complex at the same time. It is a tiny silicon device that is a miniature switch that can do 2 different jobs, an amplifier or a switch. If it works as an amplifier it takes a tiny electrical current and produces a bigger electric current. I.E. it is used in hearing aids. It also has its job as a switch it can be found in basically every computer ever made. They started as nothing now they are in everything you own.
I would categorize it under Physical Sciences and maybe some parts of chemistry because of how it is made. Circuitry.
How has The Transistor changed over time? Well it has decreased in size. When it was first created back in 1947 it was still considered large but compact and as time took its toll on the Transistor it became more and more smaller. Now these day we have Transistors smaller than dimes! There were no key people in its evolution it was just taken in by companies and they worked their magic to make the Transistor smaller and more efficient. How have improvements in technology and increasing scientific understanding led to developments with this technology? Like I stated before it was improved upon by companies who took it in and make it smaller and compact. The transistor took a major roll in electronics. Basically if it didn't exist today our computer and phones would be huge and bulky and run the risk of over heating.
