A Tutorial on Tutorials?
This might be a good opportunity for me to make a mini-tirade of my own (proving once again that the only thing I am unable to resist is, temptation).
When people learn electricity and electronics in a classical setting, there is an order to the learning. The expectation is that the students are going to learn about circuit theory and practice and that's how the process starts. And, it's a very mathematical process; series and parallel resistor calculations and reactances (capacitors and inductors) in a DC environment and tube and transistor calculations. Then it moves on to AC practice and the math tends more to trigonometry (phase angle and such). As the courses progress, they become more specialized (RF, microwave, electro-optics, power distribution, etc.) and even those branch out into more specialized fields (radio astronomy, medical, radar/sonar, weapons systems, etc. etc.) and then to even more specialized areas and a lot more etc.'s.
What's not covered very well is the physics behind the circuits. The expectation there is that the physics will be learned in physics classes and , the student will be able to fuse the circuits and physics together as needed. It doesn't always work but, that's a whole 'nother topic.
Because of the way electricity and electronics are learned, there is an expectation that someone who is truly interested and committed to learning electronics will, either by attending classes or by studying basic electrical materials on their own, will come away with at least the basics.
Unfortuanately, a lot (dare I even say most) people who try to "wing it", end up floundering. They always seem to be trying to make things fit some imagined model of the way they think electricity and electronics work...or should work. To be honest, there's plenty of floundering even among people who have taken electronics classes (including myself).
But, when you post in these forums and you don't even know what questions to ask or the terminology to use or how to understand the answers even when they really are at an extremely basic level, it really does no one any good. It creates a meaningless jumble of half-assed, indecipherable data.
So, the first recommendation is to take the advice to learn some basics. Take a class, look for interenet tutorials, read a book, find or make a knowledgable friend. As you show that you are taking some responsibility to align your knowledge base with those who seem to have some idea of how things work, your input will be accepted a lot more graciously.
They say there's no such thing as a dumb question but, there's a difference between asking a "dumb question", getting an answer and then continuing to ask the same question over and over again because you just don't make an effort to try to understand the answers that are given....that's dumb.
Thre's a lot more to say on the subject and there are a LOT of snippets and generalized statements and opinions but, it sort of sums it up. But, it's getting tediously long and even a dumb bunny such as myself knows when to cut i
