hey friends didn't see you there but now
that there's light we can see each other
crystal clear have you ever wondered how
lightbulbs came into existence come
let's find out
zoom in back in the days before the
light bulb was invented use of candles
were quite common in households in fact
they are used even today when we
experience a blackout but candles can be
very very messy though candles are
beautiful to look at they can be very
dangerous
hmmm I can smell something burning
[Music]
see what I mean
and that is why we need to thank Thomas
Edison for inventing the first ever
light bulb that has since enlightened
the world I mean it has helped light up
a world literally Thomas Edison the
inventor of the light bulb is also known
to have developed more than thousand
other inventions apart from the light
bulb some of his famous inventions
include the voting machine electric
battery and the movie camera
Thomas Edison wasn't a very bright
student he found it to be a painfully
dull routine to go to school however he
had a very curious mind and was always
inquisitive to conduct science
experiments under the tutelage of his
mother it was this inquisitive nature
that led Edison to illuminate our homes
the principle is quite simple actually
it is the electricity that flows into
the filament and when the filament heats
up sufficiently it begins to glow and
thus we have light but to make his
invention Bible
Edison faced a major hurdle he had to
make the bug glow bright enough and long
enough resulted overheating
Edison experimented with different kinds
of filaments to find the perfect match
for his light bulb
he tried copper platinum and at last he
tried filaments made from metal after
trying out many options something
finally clicked and Edison returned to
his original choice the carbon filament
was the winner amongst all but before he
could officially declare his invention
Edison had to put his invention to test
and see if it was long lasting on 22nd
October 1879 Thomas Edison ran his first
successful test on the lightbulb
the firmament born strong and bright for
a good 13 and a half hours and that was
bought as the great grand invention of
the light bulb and friends that's not
all I have something interesting to tell
you what's that dream your time twenty
three light bulbs were developed before
Edison's Sir Humphrey Davy created the
first electric arc lamp in 1809 and
Warren Delarue designed the first
incandescent light in 1820 after over
half a century of experimentation Sir
Joseph Wilson Swann created the light
bulb that was more of an industrial
nature which was used to illuminate the
Savoy Theatre in the City of Westminster
the very first public building in the
world to be entirely lit by electricity
[Music]
Edison tried 4700 different materials to
find the perfect filament including hair
from a beard like bulk production has
evolved over the years latest being the
Millenial LEDs so the next time you
switch on the light at home you know who
invented it bye for now kids until next
time when I will bring another amazing
invention for you this is me zooming out
