The atmosphere of the earth is made up of gases which reside in layers of gas that surround the planet. In order to understand the gases of the atmosphere, it helps to know how the atmosphere is constructed and what goes on in the layers...
Alternating current (AC) and direct current (DC): A simple explanation
By: David Kopczyk
The battle for dominance between alternating current (AC) and direct current (DC) may never come to a close, as they both are important in today's electronic-fueled society. A short explanation on electricity is necessary to understand the more important nuances of alternating and direct current...
