3. Electricity is a second energy source, which means that it is not given
as ready to use by the nature. Primary source such as, oil, coal, natural gas,
solar radiation, wind power, and tidal power are processed through
transforming it through chemical or physical process to generate the ‘second
energy source”, the electricity.
Benjamin Franklin is credited for discovering electricity in the 1700s
with his kite experiment, in which he flew a kite with a metal key tied to it during
a thunderstorm. Electricity was first introduced into people’s homes near the
end of the Victorian period in the late 19th century. The world's first electric
street lights were set up in London in 1878 and can be found almost
everywhere in the world today.

History of Electricity

6. Electronics’ actual history began with the invention of vacuum diode
by J.A. Fleming, in 1897; and, after that, a vacuum triode was implemented by
Lee De Forest to amplify electrical signals. This led to the introduction of
tetrode and pentode tubes that dominated the world until World War II.
Subsequently, the transistor era began with the junction transistor invention in
1948. Even though this particular invention got a Nobel Prize, yet it was later
replaced with a bulky vacuum tube that would consume high power for its
operation. The use of germanium and silicon semiconductor materials made
these transistors gain popularity and wide-acceptance usage in different
electronic circuits.
