    P=IV, not P=V*I^2. Power = Current x Voltage

    "Thank You", thank you very much. This is my 2nd time watching this, and, I would like to learn and see a static voltage regulator comparison. Let me know...

    I've been watching this series as a refresher and so far have been very impressed, but at about 11:00 your power formula is incorrect, p = ixv or ixr2 not i2xv. Other than that an excellent series so far

    Good, very good. "Thank You", thank you very much...

    Thanks I think this is exactly the info I was looking for. I have never done any electronics, and want to build a pinball machine. Starting with just flippers, but was having a really hard time figuring out what goes in between the wall current (120v?)and the flipper coils (~50v - 25v). I think a switched mode power supply is what I need to investigate... Thanks!

    I think the minimum voltage is 1.25v for the LM317 to a maximum of 35v.

    should really be a 0.33uF cap on the input and 0.1uF on the output. This is per Texas Instruments and most other manufactures for the 7805.

      That is the recommended circuit. But you can do other things to get closer, Like a voltage divider and. zener diode.

    Thanks for your time in making this. However, I think this video would have been much shorter and more effective if you planned it out a little better. For example, making the drawings beforehand and scrolling to them as needed (or cutting the video).
    Anyway, don't let all the negative comments stop you from making these videos!

    Great video! Would it be viable to use a fixed voltage regulator like the 7805 to guarantee a stable 5V to be used as a VREF for another component? (an AD board in this case). I'm running some calculations on analogue signals being read, and I need to get as close to the 5 V VREF as possible, is this a way to do it? Thanks for a great video!

    POWER = CUrrent square times Resistance

    Thank you. I had the formula for power with resistance written down.

    Hi, which regulator shall I use, to regulate voltage from solar panels. The solar panels give about 4V, and I need 3.3V, so i´m thinking in LDO regulator.
    Thanks

    How about looking at a Tesla electrical design or something else along those lines. Would be cool to see how something unusual he designed worked... not sure what exactly. :) Would be cool to start doing some projects. Useful stuff would be cool.

    Great tutorial thanks, Can anyone tell me please how to check the lm317 is working and not dead. Thank you John :)

    How to make 48 v DC to 12 v DC converter circuit, please help.

    Hello humanharddrive, are you still in the video business? Thank you.

    What was the link to the simulator?

    Power = Voltage * Current , not Voltage * (current^2)

    It's poor . Really poor.
