@Maxim Didur, the reason people seem annoyed, is that most people spend a lot of time reading the many microphone threads here to learn about microphones, before asking questions.
Most of your questions have the curiosity that brought everyone to the forums, but they are very general; they lack specificity. In other words, you are asking general questions that are already answered in books.
If you're like me, reading books can be painful. I want to know the answer to a specific question, very much out of the logical order of a book, before I can absorb the information the author has laid out for me. There's nothing wrong with that, but trying to get others here to follow your individual route of learning can be tiresome. Especially when so many contributors to the forum have little time and are already overly generous with their knowledge.
Consider reading through some project specific threads. Try a U47, M49, then U67 thread. If you have questions about any of those projects, you can ask them in the corresponding thread. For example, search "U47 build thread".
If you want to learn specifically about the amplifier of a specific microphone, you could try to start a circuit analysis discussion in an existing thread or here. If for example, in this thread, you asked specifically about the M49 electronics. Maybe disregard the physical operation of the capsule as a transducer (assumed it was a generator), then analyze the rest of the M49 circuit. DC and AC analysis. That way you can ask specific questions and get specific answers.
Open ended or generalized questions are too hard for people in a forum format.
