@#8049 That is why I explicitly specified *phone* headset. That's the one with the combined plug. While computer headsets have separate plugs for microphone and earphone, thus for those indeed there's no difference to separate devices, as far as this question is concerned. (more) |

Thank you for the answer. On the phone headset, the difference is that the connections for earphone and microphone are in a combined plug. I don't know how they are arranged; I could imagine that inserting the wrong plug might short-circuit some lines that shouldn't. OTOH the plugs might be designed ... (more) |

| Question | — |
Can confusing the plugs for earphones and microphones do any damage? The plugs for microphones and for earphones are the same, however their functionality obviously is quite different. Now because of the same plugs it is easy to insert one of them in the wrong socket. Now I'm wondering if such erroneous insertions can cause any damage. Also with the headset pl... (more) |

Thank you for the answer. Up to now I naively assumed that all transistors of the same type have essentially identical characteristics; after all, unlike for other components, there seem to be no numbers written for them on circuit diagrams. (more) |

Thank you. And yes, I meant doped. I'm not a native English speaker, and in German it's called “dotiert”, which I mistranslated to “doted”. BTW, it would have been nice if you had included the definition of $\alpha$ and $\beta$ in the quote; maybe if you are experienced in Electronics, you know immed... (more) |

| Question | — |
What is the difference between emitter and collector of a transistor? In all descriptions of how (non-FET) transistors work I've seen, there is an inherent symmetry: There's either an n-doped layer between two p-doped, or a p-doped between two n-doped, and the description does not make any distinction between the two outer layers. On the other hand, one of the conne... (more) |
