Tutorial on schematics basics
The funny thing about schematics is that they are much easier to draw than they are to read. There are many common circuits. When an experienced engineer looks at them, it’s like a second language. When someone less experienced looks at them, it looks like random lines and symbols thrown together at the last-minute. (Or maybe that’s just the schematics *I* draw.)
Other than reading Schematic Symbols themselves, one of the basic skill necessary to read a schematic is recognizing series and parallel circuits.
In short if the same current flows through all the parts, they are in series. While if current has different paths, they are in parallel. Keep reading to dive into this tutorial on how ohm’s law applies to series and parallel circuits.
