I received a simple electronics kit as a gift. It includes 80+ schematics but no explanations. I'm trying to calculate voltage, current, and resistance throughout each schematic but I hit a roadblock after only a few pages.
In the All About Circuits book, I'm up the DC Network Analysis sections. It's all straight forward enough for resisters, batteries, and other components with only 1 lead in and 1 out. However I can't figure out how to apply the rules with components not like that.
- Quad op amp. If only one of these is being used, I have 2 leads going in, 1 out, V-, and V+. If several are being used, I have the added complexity that they're sharing the V- and V+
- Transformer with 5 leads
- Transistors with 3 leads
- Logic gate (This one isn't in the kit, but while we're on the subject...)
- Diodes. Here you can't start by assuming either flow direction will work
How does the math work for these?
