    Closed: Re: Knowing Server computing power

    Hi,
    I'm talking about running scripts based on Python and GUI's based on Java which eats a lot of memory.
    I don't use graphics.
    So it is a huge database access to "HDD and SSD".

    my shunt is 0.35 mOhm and I'm driving 38A in my circuit (100 is the maximum the FET can use). so the power on shunt is (38^2)*0.35/1000~0.5W where all the power dissipation is on the FET.

    in my circuit the "Vgs" is a regulator.
    where sould I connect the negative side? directly to the source of the FET or to the ground of the circuit?

  14. Closed: Re: Need help understanding volume controls on a bluetooth board.

    can you look at the biggest components on the board and read the OPN there? you can make a picture and upload it to here so maybe we can help you.
  15. Closed: Re: Need help understanding volume controls on a bluetooth board.

    All what you need to do is to open the datasheet of the Audio Receiver chip on your board and look at the pins description of it, then see how things works.

    Closed: Chunt resistor measurement

    Hi,

    I'm trying to check the resistance of a chunt resistor using AgilentU142B, it shows me a value of 1.6 Ohm but it doesn't make sense because it should be a few m Ohm.

    what is the issue?
