    Coke versus tap water resistance

    When working in the 10,000 clean room We use copious amounts of double distilled water, 10 Mega Ohm's per centimeter square. For kicks and giggles I decided to Ohm out The water with my meter, the probes a centimeter apart from each other using a microscope for positioning. It measured 10 Megs...

    Cannot get this circuit to power up, plus some components I cannot identify

    A game of light and shadows perhaps but that transistor looks like all three pins are shorted against the heat sink.

    Overload recovery refers to the ability to recover from a short circuited output. In the recovery process the current limiting used to protect the output from drawing too much power. The current limiting circuit reduces the output current as the input to output differential increases. During...

    Coke versus tap water resistance

    Yes it will increase the electrical conductivity of water the carbon dioxide will break down into an weak acid or electrolytic Solution & in doing so it will emit negative & positively charged ions further increasing the conductivity of water

    EAS 8.2 MHz antenna design help needed

    Antennas are responsible for emitting and receiving waves that allow us to detect RFID chips. When an RFID chip crosses the antenna field, it is activated & emits a signal. The antennas create different wave fields & cover different distances. NF(Near Field) antennas are used to read RFID...

    USB 3.1 gen 1 port wiring for charging

    Loads (like a smart phone or dumb phones) draw varying amounts of current, & will have a maximum current draw rating. They will never draw more than this, but will draw much less (like when fully charged). USB ports cannot provide more than 500mA of current unless you signal the device (using...

    I will read this right now . Is there a link for that document? I meant no offense. It is just banter.

    Didn't make a note of single subject in engineering, graduating soon what to do?

    They would get nervous around midterms and finals. Final exams: That is the time when... The notes of the professors become the notes of the students,without passing through the minds of either.

    Okay I'm confused.... If he helped himself he wouldn't need anyone's advice. Is that,what they call an "Catch 22" ?

    Outstanding:... The direct approach... On top of that... Thorough:p Come on now you started it... I mean that in the best possible way! Between you and me let's just keep this Undercovers.

    Cannot get this circuit to power up, plus some components I cannot identify

    Please provide a link to the original schematic. No 12 volts on test point number 2. I have to take your word for it.There's no TP2 designation on the schematic. Why did you alter(reverse engineered to a fashion) the schematic?What would you like the schematic to do. You say it is from an Audi...

    First diagnosis steps, how to?

    Schematics are two-dimensional circuit design showing the functionality & connectivity between different components. Physical constraints & requirements mean that the PCB design generally looks quite different than what is mapped on the schematics, the design includes a silkscreen layer. This...

    After revisiting , rereading this thread in its entirety. I don't blame you. I read like I am a jerk. Really no joke. There are others here who would be happy to answer your questions. Far more knowledgeable and experienced than myself.
