Really nice work there, my friend! Pretty interesting! 😃

[@Hipyon]

Very informative Love this video

[@delipistacna]

Love your channel :)

[@RingZero]

Great video. Thanks

[@gaytrivishwakarma3072]

Very use full video I like very much!!!

[@electronic7979]

Useful video

[@MedSou]

Thank you 👍👍👍👍

[@thilinajayasingha678]

Very useful thnzz

[@mukhammadfaisal9735]

can you make dc short protection,for diy bench power supply

[@dragan3290]

I can see a business opportunity in Australia with JLPCB!

[@SIKHGT650]

Can you make diy esc

[@revolution5547]

Good video man😀. I have same amp i will make a portable 6" subwoofer(amp is realy good, like your vids.☺)(my English is realy bad)

[@guilldea]

But that formula is taken from P=U*I and assumes U and I to be in phase, the actual formula for AC power is P=U*I*cos(phase), which can be rewritten as P=cos(phase)*(U^2)/R, you are lacking therefore the cosine factor and the power is actualy weaker. Am I correct?

[@idm652]

Very good observation.

[@Centar1964]

Voltage and current are in phase through a resistive element so the volts^2/resistance will be correct. Same as D.C.

[@guilldea]

@@Centar1964 it's been a long time since I posted this, I think my concern was that the actual power delivered to a speaker is going to be less since it's a reactive load

[@WolferAlpha]

I have a water heating resistor that has 4 ohms (alarmingly accurate 4 ohms), could I use it to do the test instead of the 100w resistor or could it interfere with the test because it can vary the resistance as it heats up?

[@WolferAlpha]

By the way, great video, well explained. I would definitely send the link to this video in case a friend needs a more detailed explanation.

[@Centar1964]

Yes actually better than a resister...

[@garyyoull5067]

Reminds me of college. ,back in the day..lol

[@ErkanOkman]

👍👏

[@gamerpaddy]

"allowd up to 26V" those caps are only 25V rated

[@Centar1964]

And she even mentions the 25 volt rating at one point but then goes on suggesting that 26 volts could be tried...doesn't make sense...

[@pirateman1966]

Sheeeet! I can't even buy a coffee for $2 !!

[@bq1000bq]

The multimeter used "Fluke 17B" does NOT measure true RMS, so the figure calculated is not accurate. Also the current-voltage phase difference is also NOT factored in the calculations, again giving a poor calculated reading.

[@mousamupadhyaya8053]

Cheap multimeters even the yellow one can measure "relatively" accurate RMS in this case because the wave was sine in nature, I agree another wave-like a triangle, arbitrary waveform it cannot measure the true RMS. Talking about Current-voltage phase, the load was resistive, not inductive, i.e no speaker was connected at the output so this test was fair I think

[@kaybhee6]

power factor...

[@Centar1964]

Is 1 in this case. Resistive element....
