I have been reading the first chapter (I think) in the DC volume. It is talking about voltage drop and comparing it to how if a rock falls or water falls from a certain height it has a more violent impact the higher the object is dropped from. This does not make sense to me because a voltage drop means (if I am correct) that the amount of voltage drops over a given distance. Also, maybe I misunderstood, but in the beginning of that chapter it was talking about static electricity and the origin of negative and positive.
Benjamin Franklin hypothesized that the negative had a deficiency of fluid, while the positive had an excess of "fluid". However, since electrons have a negative charge, having an abundance of them makes the negative side negative. Then later on the text says something and then in parentheses (thanks Ben!) like the idea of positive and negative is incorrect. Also, when I was doing my really simple electronics project i.e. getting 2 IR LEDs to light when connected to a USB cable, I was calculating the voltage drop over the LED, which I cam to the conclusion that the voltage of the LED was the drop, so then I had to account for the remaining voltage with a resistor. Is the voltage drop only the voltage needed by the LEDs because the distance to the beginning of the circuit is not very big?
Regardless, it might help to make the volumes (at least the DC one) not as confusing. I am a beginner and I am having a hard time.
