    circuit breaker switched off from distance ?

    bad advice: Just "paint" the cabinet with som really sticky glue or similar - so that whenever someone touch it, they leaves visible marks. - or on the lever itself :D Remark - it's a bad advice because adding weight to a mechanical lever may alter the funktion of a circuit breaker (very...

    entrepreneurs and companies that work in the field of electrical engineering

    I agree what the blue eyes above say. There is dosens of videos on youtube and sources on web that you can learn from. Watch those, and then if there is some specific things you don't get to understand - THEN it makes sense to ask on this forum. Furtermore - there is one more thing that makes...

    Equivalent Circuits

    Image you have a load that have a certain resistance (you are to decide it's value). Then ask yourself this question: - Will the voltage over the load be the same in both cases? - Will the current through the load be the same in both cases (?) - If the terminals is shorted, will there flow...

    What do you reckon the most produced component is?

    Is there any statistics on this - btw. what are we counting in numbers or mass. Maybe the pcb card itself is the most produced, in terms of volume. And if the question is about numbers - I'll keep to the pcb by claim there must be the paths/traces that outnumbers any components. [edit] Just...

    Rewiring

    Why do you want to do that? Is it the input connector that doesn't fit?

    12v dc to 10v dc converter

    Good to see someone ask for a clean language, I'm not a native english my self, so urban non-standard expression (like cool words with appearently little or no meaning behind) make it hard to understand, even if the nature of the problem is very simple. What is your requirement of amperage and...

    Mains Voltage

    I have to be honsest : Given the level of experience you appear to have, I strongly recommend to not "play" with any mains voltage. Why do I say this: Because even minor currents through the body may have long term consequenses of your health - so it's generally not worth the risk.

    Infinite Switch

    Why not just not only parrallell them electrically, but also physically (if close and enough space around)? This would be a good practice in Blender - but I'm not there yet.

    Crt tv power problem

    I don't know what the plugs look like, but DO NOT OPEN THE CASE of the aparatus, as it still may contain high voltage.

    Principles of relays [Understanding Textbook]

    Yes - I'm just as puzzled, looks like some bad translation or something. It probably should be expressed in a different way, I'll assume something like this ". . . . current of about 1600A flows through the CT". Anyway - the last part of the sentence doesn't make sense because the relay will...

    Differential Amplifier

    For the question D (the printed part not translated) it says that the 8.2kΩ resistor is switced by a current source. btw. It's a bad practice not to labeling all components, as the resistors (that is to blame the assignment paper).

    How to connect tweeter with speaker, series or parallel?

    I have tried to connect a AA battery cell directly to a piezo tweeter. It really doesn't happens anything (like smoking, heating, etc...). There is a barely auditible click at the moment of contact, and same when battery is removed - if I remember correct.

    I need someone to help identify the layout of this board.

    I really didn't quite get the problem. Are your wall adapter gone? Does the power adapter plug loose and need to be soldered back again? None of the issues above normally requires a schematic. So you use the term "switch" - probably wrong word as that indicates...

    Noob seeking circuit advice - if 0v then 2.5v otherwise 0-5v

    The problem you have is doable using opamps, logic gates and discrete components. The problem with "0 volts" is that it is hard to detect excactly 0 volts (*). But if you have access to a negative voltage supply, then you can easilly make a opamp scmith-trigger to detect a voltage close to 0V...

    Determining The Accuracy of Amp Meter

    How much current are you planning to test? What is the brand and name of the amperemeter? Could it be just easy to download its paper from the manufactors web site and just see what it says? Do you have access to a more accurate ampere meter to test against? That is what I would have done. And...

    Tips on tracing complex PCB circuits:

    Can I ask if the first thread is gone? Was looking for a question but cannot find it. anyway - paint shop pro is not free, it cost money. Gimp can do pretty much the same, but doesn't cost nothing. But for this specific task, I'll recommend using Inkscape. The workflow will then sort of...

    Need help on series circuit

    Yes, you got everything you need. One method is to makke out the formula of voltage divider - what voltage over R with respect of the value of R. Then insert this formula (replace by it where "R" would be) in the formula where you would solve the Wattage with respect of R/inserted formula...
