A slight disagreement with your description of AC at 2: 35. With a 2-wire voltage like this, what is zero volts? In this instance, it is only a mathematical construct. There is no 0VAC connection anywhere. 0V is only a reference point for the math, where y = Asin (wt) describes a floating AC voltage. But a meter or the generator itself has no idea what 0V means. Similarly, there is great misunderstanding of what ground means, too. What is ground? Does an electron know what it means? No, it is only a convenient reference point that we humans use to make a schematic look simpler. Ground, or 0V, means nothing to an electron. Electrons will go where electrons go. 0V is only where your meter's black wire probe touches! You can put that probe anywhere if you so desire. Many an engineer goes wrong by assuming his GND signal means there is zero voltage differential between various GND points of his circuit. If there is current flowing in the ground plane, then you betcha that there is a small voltage differential across the ground plane. Tiny, but finite. Audio engineers understand this subtle point because differential ground voltages can and will enter your audio circuit if you don't know what you're doing. I do concede that using the ubiquitous Ground symbol makes for a cleaner schematic, while also defining what you, the designer, want to define as zero volts.

Would a 100volt 3, 700 or 5, 000 or 10, 000 Farrad capacitor be dangerous? I need 100volt because a bicycle bottle or hub dynamo can output up to around 100 volts ac on very fast down hill descents. I plan to use it to make a full wave bridge rectifier as a smoother for my vintage bicycle dynamo lights to stop the very annoying strobing that occurs with the AC & to hopefully enable the light to glow for a few minutes when stopped at traffic lights when the current from the dynamo is no longer flowing - the capacitor discharging into the load ( a 3 watt total of front & rear led bulbs. How long could I expect the lights to glow for before going out completely with these value capacitors please?

I feel like all of the videos I find like this teach the theory of the board, and rarely approach the details. How do I decide for my application what size resistors I should use? How can I determine the right size capacitor and number of capacitors to use? Why do the capacitors need to be in parallel? What would happen if you put them in series instead? What is an inductor? How do I choose the right one for my application? I know what a transistor is (sort of, but again, how do I choose one for my application?

Ive been watching your videos here and there for about a year now and Im finally at the point now where I can stick with you during the video and even guess what youre going to say and actually understand whats going on. Thank you so much for making electronics simple and easy to understand.
By the way if youre watching his videos and feel like youre not understanding anything, just keep watching and trying to learn and they will begin to make more sense with time

This is excellent, but I'm trying to understand something: At 15: 10, how is it that when the power is switched off, the current discharged from the capacitor will go the path to the bleeder resistor rather than to the load? Also, why wouldn't the current take this path while power is on? I'm just trying to understand the behaviour of the electrical current. Thank you for this video and any help.

A great intro to the subject. One thing I always find lacking in any coverage of AC is the reason why power companies use it.
Basically it boils down to distance between generation and end-use. AC voltage is easier and more efficient to deliver over longer distances than DC is. not as much power is lost transmitting it over longer distances.

As stated, the components in consumer electronics use and expect DC power. Question: Is it theoretically possible to produce consumer electronics that fully function on AC power? If so, why didn't we do that? Is it simply not technically possible? Is it inefficient compared to DC? Or would it need a totally different approach to electronics?

Pi filter not named pi filtee because it looks like the greek letter pi. The Pi reference is for the greek letter, but only because of the mathematical reference. Pi represents 180 degrees or half of a circle. Pi filter is so cleverly namrd because it filters half circles( half cycles.

Hey Paul, I made a circuit using this tool on my phone called proto, highly recommend it, I user 5v AC and I think my led hated that so I cranked the max voltage as high as it would go and used a 100F capacitor since you cna easily use those and boom DC baby

At 16: 03 why does the multimeter calculate using rms voltage 12v ac without capacitor to 10. 5v dc but with capacitor it calculates using peak voltage 16. 9v ac to 15. 5v dc, how does the capacitor make the multimeter do that?

i have studied eletronic for so long but the way you explain about the components and circuits is of another level. keep the good work and il try to be a patreon as soon as I can. cheers and stay blessed always.

One slight mistake at time stamp of about 3: 37: You say RMS voltage is obtained by dividing peak voltage by 0. 707 when in fact it is multiplied by 0. 707. The graphic in the video is nevertheless correct.

I agree, best videos all-round. Just a correction, at 3: 35 you say to find the RMS voltage 'divide by 0. 707', but it should be 'multiply by 0. 707 as the video shows. Am I correct?

When we plug in a transformer why is the main coil not shorting out and using huge amounts of wattage? Because of resistance?

I'm scary of playing with AC power. Can I do convert DC to AC then back to DC again to try it?
Can AC be low voltage?
