Understanding the basics of electricity
In order to understand series/parallel wiring, it becomes necessary to understand the concepts behind electricity.
Electricity has two components: amperage and voltage. As a comparison, you can consider voltage to be the pressure of the flow of electrons, while amperage is the size of the field, as demonstrated by this visual description.
You can adjust the voltage and amperage of your array in the way that it's wired.
