UBT1 Task 1: Electricity

Introduction

What is Electricity? This question is difficult to answer because this is a broad concept of science with multiple definitions. In physics, Electricity is a naturally occurring phenomenon of the flow of electric charge. In other words, the process of attraction and repulsion between electric charges produce electricity. There are two types of charges- negative charges and positive charges. Like charges repel each other, whereas, unlike charges attract each other due to the presence of an electric field.

1600- William Gilbert can be correctly called the father of electricity as he “first coined the term "electricity" from the Greek word for amber. Gilbert wrote about the electrification

V=IR seems a pretty simple law to name after someone, but the importance of Ohm 's work does not lie in this simple proportionality. What Ohm did was develop the idea of voltage as the driver of electric current. Ohm had to face a lot of opposition. This discovery was not accepted until 1841 (“A Timeline Of History Of Electricity,” n.d.).

1831- Using his invention the induction ring, Michael Faraday proved that electricity can be induced (made) by changes in an electromagnetic field. Faraday’s experiments about how electric current works, led to the understanding of electrical transformers and motors. This experiment became Faraday’s Law, which became one of the Maxwell Equations (Administrator, 2007).

1890 - Heinrich Hertz (1857-1894) a German physicist, laid the ground work for the vacuum tube. He laid the foundation for the future development of radio, telephone, telegraph, and even television. He was one of the first people to demonstrate the existence of electric waves. Hertz was convinced that there were electromagnetic waves in space. Even though Hertz did not think his discovery was useful, it was a major discover in the field of Radio Technology. It later on it helped develop wireless communication (“History of Magnetism and Electricity,”
