Lithium ion thermal runaway is often caused by dendrite growth puncturing through the batteries internal barrier, shorting anode to cathode and allowing the energy to release to itself at full force. External pressure loss of the battery also promotes dendrite growth, although we don’t know every possible risk factor to make it worse yet from what I’ve read so far.

Modern LCD monitors do not blink. The higher frequencies are mainly for gaming. The old CRTs did blink but that really was not because of AC, In general 70 Hz was seen as stable (note incandescent bulbs flicker at 120 Hz in the US and 100 Hz in Europe) though I could see the difference between 75 Hz and 85 Hz. You see the flicker mainly on your peripheral vision so the larger the screen relatively is the more you notice it. Btw the mains frequency in Europe is 50 Hz because at 40 Hz lights did flicker.

Good day sir, I am one of your subscribers here on youtube....I am only a electrical guy working on automotive industry..I am wondering sir what is importance of checking a frequency (Hz) when your diagnosing...beacause almost I am thinking checking available voltage,or voltage drops,shorted circuits or opens testings so we can figured out why this problems occur...thank you sir always watching and learning your videos god bless😊😊

To clarify, commercial aircraft cargo bays are same pressure as cabin. Lithium battery rules are to allow cabin crew to put a run a way battery in a “fire” bag.

10:34 Lets say i have 2 setups of batteries, first one is in serie and second one is in parrallel. Both have same power ( P=E•I ) . Witch setup would you consider more dangerous? ( Faultwise and lifewise ). Remember.. one has less voltage, but more ampacity. The other, more voltage, less ampacity. 100V 10A... or 10V 100A.. ? No overcurrent protection.

You bring up an interesting point: batteries in parallel vs. series. Can you go into that a bit? Why doesn't that increase voltage at the target? Why go through that much work to convert AC-> DC when you just pass it through a rectifier?

@jhoughjr1

10 ай бұрын

on parallel vs series; voltage is a measure of potential energy. It's literally like a runner band stretched between too different charges. So when you put batteries in series, you are stretching the band further by adding. more links in a chain. Each link only sees the weakest amount of tension so to speak, its own voltage. Because voltage is potential it is kinda relative. So the potential across 1 battery is always the same. But the potential across 5 batteries is 5 times as much. Just like a step 1 foot high is the same size whether it is a porch or a skyscraper staircase; falling 1 stair is always 1 stair but the whole steps can be a further fall. on why do all the work; he hints at it, it is so we can do transformer magic. You can do the same job with a transformer a rectifier a capacitor and a voltage regulator. But while that is fewer parts, it's actually larger, heavier, more difficult and expensive to manufacture in bulk and less efficient than the switch mode supply doing all of its transformations.

No, AC is more dangerous. AC is generally seen safe up to 50 V while DC up to 120 V. AC causes the muscles to contract at the frequency. With high enough voltage both are dangerous.

The only bummer about replacing parts in a power supply is that companies usually seal them, and you usually have to mangle the case to get it open.

My favorite AC/DC is "Live Wire" Ohhhh stick this in your fuse box!

AC/DC Rocks bro!!

your graphs drawn so well. what sorcery is this?

5:00 Why do we mostly use those kind of transformers ( primary coil, inducting on an other coil "secondary" , when we could use auto-transformers ? Only one coil "single phase, but 3 for 3 phases obviously" , high voltage hooks up to both ends of the coil, and you tap where you want on the coil to have lower voltage. ( Want half of the high voltage, tap your secondary wires half way.. Alsmost half the weight and copper in an autotransformer, than in a common transformer.

Everything is electricity. Everything is light.

Ask your dog how to change the starter in your car. You might get a better answer. This guy might know all there is about wiring, but his theory is very bad.

While it is true that alternating current produces a flicker, it is also true that the element does not have enough time in which to cool off to the point where light is no longer emitted. So the cycle is really dimmer and brighter as opposed to on and off. But then again, everybody has watched a toaster anticipating that magical pop when the toast is done

​@@thebaddestogre-3698LEDs are a DC component. They are light-emitting diodes. Diodes are unidirectional and do not allow current to pass both ways. Any flickering you might see on LEDs would not be directly related to the polarity shifts of AC power.

DC is more dangerous than AC, in terms of sustaining an arc and arc flash. AC arcs are easier to extinguish because of the 0 crossing that occurs 120 times a second, assuming you're dealing with 60Hz. Whereas DC arcs don't have that zero crossing particularly with pure DC such as several large 12volt batteries in series. It's for this reason fuses and circuit breakers suitable for AC/DC have lower voltage and interrupting ratings for DC, such as 250VAC- 200kA / 125VDC-20kA.

I have a question, I checked on some solar panels with a voltage pen and it was picking up AC current. that isn't supposed to be doing that right ?

It would be suggesting that your panels/racking is in contact with an AC voltage source.... of potentially harmful voltage levels! Exercise caution when trying to track down that AC source! DO NOT CLEAN until rectified. Are the panels ground mounted or roof mounted? Using a volt METER, measure the AC voltage between the panels/racking and literal earth (Yes. Stick one probe into the earth and the other probe on the panel/racking). If you are not totally comfortable with performing the tracking down activity, then please utilize the services of a licensed electrician in order to assist.

He totally did get this wrong, good catch! A/C doesn't pulse after going through a rectifier, at least not in the way he had it drawn out. A rectifier makes A/C into something closer to a varying D/C, which is then smoothed out using capacitors. An inverter will make a sine wave like he had drawn, but I think he is confusing how a rectifier works with how an inverter works. Cell phone charging bricks don't have inverters inside of them.

I ran two 2-gauge DC wires in separate metal conduits, one for the 12 volt positive and one for the 12 volt negative feeds to our 12 volt DC devises in a mountain cabin. I have since learned that you must NEVER run hot and neutral AC wires in separate raceways due to induction. Am I OK to leave my installation as is since it is 12 volt DC? Do I need to worry about induced current when dealing with DC? I am guessing it is not an issue…..just look at how DC is handled on vehicles, positive out from battery while returning negative ground current can travel back through wires or metal chassis of the vehicle, no need to be in the same raceway.

Most people use LIFEPO4 chemistry for solar, EV's, etc., which doesn't run away or burn, like lithium ion...Still dangerous if the voltage is high and you become part part of the circuit...Ya, I've been working with AC for decades, but learning DC for my off grid homestead, thankfully I'm my own inspector..

Do LED lights flicker less fast than the incandescent ones? 120 times per seconds for AC incandescent light.. Half the time for DC leds? ( Current only pass in one direction )

@rohmor

LED lights do not flicker. Current is passing in one direction, yes. But it is also Continuous! Hence no flicker. Although it wasn't mentioned (I think), there is DC referred to as 'Half-wave rectified DC' vs 'Full-wave rectified DC'. Half-wave rectification results from using only the Positive OR Negative AC wave portions. Full-wave rectification results from using both positive AND negative AC wave portions. Full-wave rectification is more costly to achieve, but results in a smoother DC rectified waveform.

@@martf1061 Light Emitting Diodes (LEDs) can be dimmed using various methods, each with its own advantages and drawbacks. 1. By rapidly turning the LED on and off (pulsing) at a high frequency while varying the on/off times. This technique is common and is called Pulse Width Modulation (PWM). 2. LEDs can also be dimmed by varying the voltage supplied to them. Lowering the voltage, reduces the current flowing through the LED, leading to lower brightness. This technique is less efficient than PWM. Other methods include Current Regulation whereby Dimming is achieved by regulating the current flowing through the LED. And Digital dimming using digital signals.

SMPSs are weird. They have to be cheaper than traditional power supplies. They're also smaller. They also ruin AM and shortwave radio. I wish they could do something about the radio noise they broadcast. Back in the day, such devices would be prohibited by the FCC. I'm not sure what happened. The SMPS is killing AM radio. I doubt it will be around in ten years. The FCC wants to put digital on AM, but HD radio never caught on. The things are uber expensive. It makes me wonder if they could convert AM radio to FM. They would have to call it MWFM or something.
