Something to Think about.

Hello everyone in the Electronics Tech Class!!! I was just doing some studying and came across something I thought was interesting. The definition of a coulomb is, that it is a quantity of charge equaling 6.25 x 10^18 electrons. That is 6.25 quintillion electrons!!!! The prefix for quintillion is Exa. It was added in 1975. Here are a few factoids containing that prefix:

• The total storage needed by Google Mail as of April 2012, ignoring backups and compression, is more than an exabyte (10240 megabytes of storage per user multiplied by an estimated 260 million users).
• 1 EeV = 10¹⁸electronvolts = 0.1602 joule
• 1 exasecond is approximately 32 billion years
• 1 exametre is approximately 110 light years
• 0.43 Es ≈ the approximate age of the Universe

I thought that was pretty awesome when you actually consider the mass of that number. That is a whole lot of electrons flowing every second through a light bulb!!! I will think about these facts every time I turn on my light!!
