So I built a multi tap MOT transformer for running all manner of battery powered tools but without the batteries and I even want to run a 12v cigarette lighter and a small tab welder good enough for battery strips all off this one transformer 9v all the way to 24. I'm using a rectifier from an old car alternator but I have no experience with capacitors. I don't understand how a capacitor could be connected across hot and neg like In the video. Wouldn't that make a short? I always imagined capacitors being connected across either or but not both at the same time. Are there differences in connecting capacitors In other ways? Also if I'm using only part of my rewound secondary coil for short circuit current is it good to ''beef up'' or double up only that section of secondary instead of then entire wire?

Question? - I have circuit diagram from 2005-2008. It has DC to AC
Inverter of 120v AC output hooked with diode on each secondary line,
that is reversed polarity ( Both different) one way, then other way.
My test meter reads both on AC and DC. How do I get proper reading
across load resistor on multi meter? This is not supposed to be
clipping circuit of very low voltage. Circuit load on paper was inductor
coil, diodes and and resistor.

I'm trying to understand why you would only read 10. 5VDC (5: 05) when measuring from the rectified 12VAC, shouldn't it also be 15. 5VDC? RMS is only a factor when measuring AC isnt it? Why does it matter if the capacitor is in paralell? I'm probably misunderstanding something here.
Your videos has probably helped me to understand some things that were previously hard to wrap my head around, thanks!

I just love you man. You made electricity so easy for me. I am an electrical engineer and my interest increased after i got my degree. All credits for my interest goes to you. Please come on udemy and provide some online courses which will be very beneficial. I hope someday you cover topics about substation, generation, transmission and protection system in details.

The Engineering Mindset thank you for these videos I have a problem understanding material for my course due to a poor seeming system of explanation as Im a visual and hands on learner these explanations with a video showing the physical difference makes a massive difference and I hope you keep making them as they are truly helpful!

Hi Sir, please can help when the capacitor discharge in above video those ot discharge from the negative or the positive? and if it those discharge from the negative side of the capacitor which diode those the current flow through? please help very confused

You forgot to discuss power factor, harmonic distortion, power factor correction circuitry, and solutions to creating an active bridge rectifier that use FETs instead of diodes and an active controller IC that can be used to eliminate voltage drop issues.

And to think i desperately needed this insight just three days ago when it was uploaded and now we're here. Thank you! Im kinda looking for safe ways to hook up a 3v led to 220v mains o. o and i gotta say there are a lot of split opinions out there

The explanation is so clear that I understood even though I am just a hobbyist tq. 12V AC drops due to diodes and the capacitor peak voltage and finally became 15. 5V. How then can I get 12V DC to power my 12V rated device?

So. is it required to have this come from the shown transformer or is it possible (as very well I assume it would be with the numerous phone chargers I have about the house) to use the AC voltage from the wall

Please help i made my own bridge rectifier when i connect load to its output the voltage drops from 13v to 0. 5v my oscilloscope shows that from full bridge to straight line.

Great video as always. Any chance you can do videos on how to use a multimeter, and a power supply? Some of the symbols on a multimeter for example can be intimidating for newbies.

Good video and how many load we can put on ac variable transformar and can we give 24 or 48 volt ac to dc which capacitor we can use?

Newbie here:
Why doesn't the current flow through diode1 and than 2 or through diode 4 and than 3?
i hope the question is clear

Superb! How can i use a filtering capacitor and have the DC voltage unaltered? Does it always have to be higher than the input voltage?

Doesn't work for me. From ac 5. 3 got 4. 65 but the moter doesn't start. But if i put it on psu from pc works normally even with 3v

6: 31 Ah, the Pi filter. Of all the filter circuits those are my favorite, simply because of how clean the output is.

Your DC meter on the rectified DC output will be reading artificially lower due to lack of filtering.

Dear, in negative side of sine wave, is current really flowing from neutral to line through the load?
