    Rectified 120vac is around 170 volts. That should resolve your issue of the current being 40% higher than calculated. Great video, though!

    hi, shouldn't you use Vin = (120 x under root 2 ) - 4 because Vin = Vp and Vp = Vrms x under root 2?

    Caution
    Do not attempt to implement or use the information, unless you are experienced and skilled with respect to such subject matter, and competent in handling AC mains. There are better ways to accomplish the same task.

    Thank you so much for your explanation, sir. Could you please explain why are you using a 220ohm resistor in series with the dropping capacitor? It would be amazing.

    Why didnt you add this 1M bleeder resistor to your impedance calculations?

    nice vid, sir
    how do you obtain the C value of the voltage stabilizer cap in parallel with the output load?

    Hi, I like to know how to calculate the capacitor value for dc ac inverters in first stage capacitor. can you pls help me?

      Thanks for subscribing. A quick design approach is to do it empirically.

      Z= √(〖220〗^2+〖3,902〗^2 ) Z= √(48400+15225604) Z=√15274004 Z = 3,908

    This makes me quit electronics... It feels like I don't have time for this even tho I enjoy it very much and very thing I learn I feel it's a bonus but for what ? I don't really make money with this or just rarely...

    1/6.28×60×5000
    1/2185440
    0.46uf
    U r getting this value
    But when I multiply
    1/6.28×60×5000 I'm getting
    1/1884000
    5.307uf
    How is this,y your values r not matching ,can u explain me

    Power loss = 120.6V x 0.028A = 3.3768W - 0.064W (LED) = 3.3128 watts
