    Sorry for the dumb question but why is the current going through the cathode of the device 0.02mA? I didn't see how that was calculated. Thanks.

    I watched other videos but lucid explains the current source the best.

      You all prolly dont care at all but does any of you know of a method to log back into an Instagram account?
      I was dumb forgot the login password. I would appreciate any tips you can give me!

      @Noah Carl i really appreciate your reply. I found the site through google and Im in the hacking process now.
      I see it takes a while so I will reply here later when my account password hopefully is recovered.

      @Noah Carl it worked and I finally got access to my account again. I'm so happy!
      Thanks so much, you really help me out :D

    What is the value of RCL and can this circuit work at 5v ?

    How can you control the cathode current in the TL431? What if I want a 5mA source. Is it possible to limit to very small amounts of current? When I simulate this circuit with 5mA target current, the cathode current of the TL431 is too high.

    hello, but what about the voltage difference between the source and the load ? can it be used to charge a 12v battery with a constant current of 0.8A and 13v ? thanks

    Is there a way to do it without the massive power resistor as the circuit could be half the size for laser diode or led driver circuit?

    • @kohizeri_daisuki
      @kohizeri_daisuki 5 років тому

      I think you meant resistor, but sadly there is no other way to make it smaller and less bulky unless you switch to other constant current power supplies like SMPSs which are dedicated for those stuff, unless you want to set the circuit on fire if you use a lower wattage of the resistor. Just saying though. Cheers!

      @@kohizeri_daisuki Yes i meant power resistor thanks my bad ! there is an ic the AMC7135 that limits to 350ma assuming you can provide a stable voltage if that helps...

      @Another Dick Thanks but i don't like the heat and wasted energy i am just trying to get efficiency in a small package.. :-)

    Can you make a simple high current CC/CV for supercaps?

  • @youpattube1
    @youpattube1 5 років тому

    Isn't the power at R1 about 0.71 watts ? Aren't you using a 1/8W resistor ?

      In my opinion it is much better to use an SMPS for this matter. Just a suggestion.
