This will probably sound really stupid coming from a complete idiot (me). But, I cannot for the life of me understand the basic concepts of Current (including Amps, Coulombs, I don't know the difference), Voltage, and Resistance. It's something about visualizing these that I have a really hard time grasping. I really need a laymans explanation as I'm looking at 3 different textbooks and have been googling for days with no avail.
"
The amount of current is the sum of the charges of the moving electrons past a given point.
An electron has a very small charge, so the charge of 6.24 X 10 to the 18th power electrons is added together and called a coulomb (C). When 1 coulomb of charge moves past a single point in 1 second, it is called an ampere (A).

This is one quote i'd really like to tackle, what are charges? does this mean that current can be "thick" or "thin"? does it mean that everything that is matter has variable amounts of coulombs but there isn't any amps or current measured without external force(voltage being the one listed in the book)? If this is the case, is there current when I apply physical force by throwing an object like an apple? I honestly need a 4th grade explanation of this.
