Quarter 3, Blogpost #4

Once again, this is a blog post that was supposed to be due last week. I really need to keep up with my blog posts for each week -__- But anyway, this week we learned about Capacitance. Capacitance is known as short term energy storage. Capacitors store lots of voltage but not a great deal of charge. The equation to determine capacitance is C = Eo x A / d. "C" is capacitance while "Eo" is epsilon or permitivity o free space and is measured using the constant 8.85 x 10ˆ-12 Cˆ2/Nmˆ2. "A" is the area of plates measured in mˆ2 and "d" is distance between plates measured in meters. The units of capacitance is coulombs per volts or a Farad. To better explain capacitance to us, Mr. Blake used our laptop keyboards as examples. He explained that the capacitors of the keyboard are located underneath each key. It is made of two plates that when pressed are pushed together and tell the computer to create the specified symbol. The two plates are originally separated by a dielectric. I am using the capacitors of the keyboard right now in order to create this blogpost lol. Well I hope I explained this well enough for you all to understand. Promise my next blogpost will be on time (: haha.
