Here I am again with another amazing invention that
changed the world. We definitely all have light bulbs in our homes and let’s
face it, we can’t imagine living without them. We all go insane when we have temporary
black outs while it’s dark outside. When all you have is natural light, we are very limited to do anything to daylight hours. Light bulbs changed the world by
allowing us to be active at night. The first light bulb was invented throughout
the 1800s but the light bulbs had a short life period, they wouldn’t last longer
than a few hours. Wasn’t until 1879, when Thomas Edison created a completely functional
lighting system which consisted of having a generator and wiring as well as a
carbon-filament bulb.

As the years passed, more people were interested on
the functionality of the light bulb and with research they succeeded to create
even better light bulbs. Now we see a whole bunch of different light bulbs with
different varieties of functions and shapes. Here are the different types of
light bulbs that we can find on the market today:
Incandescent: this type of light bulb produces light when an electric current passes through a filament and causes it
to light up. This is the common type of bulbs we find in homes because they're cheap and are kind of bright.

Fluorescent: this type of light bulb produces light when an electric arc passes between metals from the periodic table that conduct electricity to excite the mercury and other gasses in the light bulbs producing radiant energy, and this energy is converted in to a visible that we can see. We are starting to see more and more of these types of bulbs in homes because they last longer and don't need a lot of electricity to light up a room.

High-Intensity
Discharge (HID): produces light when electricity passes between metals that can conduct electricity in a pressurized tube. They have long lives and
are extremely energy efficient. You can find these on cars that have a different color headlights. I myself just installed HID lights on my dad's SUV and this type of light bulb is very bright.

Light Emitting Diodes (LEDs): this type of light bulb produces light when voltage is applied to negatively charged semiconductors to create light. You most often find these types of light bulbs on cars that have neon lights. I find it amazing how we can produce light with a variety of colors now.

I’ve pretty much covered all the basic things you
need to know about the invention of light bulbs and where we are now with the
advancement of this invention. If you want to know more about this amazing
invention feel free to do more research and I’m sure all your questions will be
answered or you can even ask me a question by writing a comment! Stay tuned for
more wonderful and exciting inventions that changed the world!

Some more unintentional plagiarism here. This is a common mistake. You've sourced your sites on the bottom and thus it seems natural to be able to copy-paste their information. Unfortunately, that is still considered plagiarism.

Great concept for your blog, but you have to add your own input. Remove all plagiarism and add more of your own opinion on each of these inventions. Reveal your sources for all of your posts (2nd and 3rd posts don't have clear sources for example) and watch out for common grammar mistakes (ex. Basis vs bases, loose vs lose)
ReplyDeleteGreat post Hussein! Come to think of it… I can’t imagine a life without light bulbs. Everything would be different in life. We never really appreciate what we have. To be honest, Thomas Edison may have made the greatest discovery of all-time. It was really a huge success. I can’t wait to read your next post.
