This has been my question since back in the day and I'm 40😅

Sorry bt couldn't understand due to accent issues. Can you put subs

u mean what realy glow the bulp is the electric field right ?

this is very well done good job!

What if you just hold on to 5he ceiling

Electricity is flow of electrons & wave on electron strings along with associated electric & magnetic fields. If we calculate the speed of wave on electron string it will come out to be equal to speed of light.

Hi, I would like to do a maths project for school on this topic, would it be possible for me to get in touch with you via email or somewhere else so I could ask you a few questions and clarifications?

Pls tell me what is abs ???

Which is more mindblown? This or the fishes at the bottom of the sea can survive the pressure being crushed haha

If the elevator shaft is normal, with all the doors shut (because the elevator is not "at" a particular floor), the elevator will be cushioned a lot by the air trapped underneath it. And if it's a recently made elevator, where particular attention is given to having an elevator "well fitted" to the elevator shaft, that cushion will be incredibly effective in slowing down the max drop speed. But what to do to maximize survival? When you start the drop, whip off your belt, lift the roof door (ALL Elevators have them) enough to trap the buckle above the roof door. Get a good grip on the belt, suspending yourself under the roof door, and hold on for dear life. The force of impact when the elevator hits bottom will almost certainly make you lose your grip on the belt, but NOT before you have expended a considerable amount of your momentum. Possibly even reducing it by half. Possibly changing a fatal accident into an impact that breaks no bones. Also aiding you will be that the elevator roof, on impact, will bend downward with you, at a diminished speed, and improve the effectiveness of your belt-grip deceleration . The object is to survive...not look cool.

I could see it being okay in light rain…but heavy flash rain?

u contradicted yourself by saying electrons moving at near speed of light (3:30)

This was great! Your student analogy was great for the individual electrons. But what in that scenario would be the electric charge that moves at the speed of light?

Dude your boring

If you had another person in there. Then you could use them as a cushion. Especially if they were really fat. Haha

This video implies that electric charge is responsible for powering up a light bulb in a closed circuit made of metal. Electron is subatomic particles responsible for chemical reaction but light bulb.

Things look bigger in the water. Please delete this video

My new (elekton) elekticity says that electricity aint due to drifting electrons, or the Poynting Field/Vector, it is due to photons (elektons) hugging the surface of the Cu. The elektons propagate in the insulation (if any) in which case they propagate at the speed of light in the plastic, about 2c/3. On bare wires the speed of elekticity is 3c/3. A good conductor is a substance that a photon can hug, eg all metals are goodish conductors i think. The hugging is strong if there are free-ish conduction elektrons in the wire -- Cu has 2 such elektrons per atom. Elektons don’t reflect, they do a U-turn at the end of the wire. Actually, elektons always go straight ahead, it is the surface of the Cu that duz the U-turn. If u measure the speed of elekticity along a threaded rod u will find that the time taken is longer than for a plain rod, the difference being exactly the extra distance up & down over the threads. U should do a youtube about this. Your welcome.

I love your channel please upload again 🥺🥺🍣🥺🥺🥺🥺🍣🍣🥺🥺🥺🥺🥺🥺🥺🥺🥺🥺😭😭😭😭🥺🥺🥺💖💖💖💖💖✋✋✋

Are you alive

Does this work the same horizontally as it does vertically

centrifugal force is applied in non inertial frame this is not the correct reason if you would find out with inertial frame

This is CLEAR

By far THE BEST video on explanation of electric current and fields, i am a teacher myself but i have no shame in saying that I've never taught my students this but thanks to you i will now. Stay blessed.(P.S i hope you will allow to use your video in my lectures)

I barely could understand your voice. Change the mic or your larynx

Great channel Hope to see more stuff Can i ask .... which animation tool have you used ? Thanks and more power to you :)

Excellent video👌...but why it has only 1k subscribers? can't understand...

Nice video..I have one question regarding flow of current, if electrons are negetively charged than according to definition of current " the flow of charge is known as electric current" why there is no repulsion between electrons and how come they travel in same direction.

The electromagnetic wave propagates due to change in the electric and magnetic fields, thus carrying energy. What happens when the fields are unchanging, I.e DC / 0 Hz? How is the energy then propagating?

Great video! Thank you! A real world analogy (not perfect, but helps demonstrate the difference between energy propagation and "carrier displacement"): Stand beside a long train made up of many grain or ore carriages while it is being shunted. When the locomotive applies a force (pulling or pushing), that force is passed from carriage to carriage as each coupling stretches or compresses, and a very, very fast "wave" of 'bang-bang-bang' travels the length of the train in seconds, while any particular carriage moves only a tiny tiny distance. It's quite an experience! (Again, this model is not perfect, but may be helpful for envisioning what EM fields and charge carriers are doing in a wire... It may be worth noting that a single cycle of 50Hz AC out of the wall is about 60,000km from peak to peak (a bit less because speed of light in a vacuum is not achieved), or about 1.5x the circumference of Earth... The few '0s or '00s of km distance between a power station and your light bulb means that the potential difference across such a short distance is miniscule (not talking 'live to neutral'!!)...

Guess, they go in opposite directions, so that's why.

What physical properties of a conductor makes it better for an electric field to "flow" (not the correct term here because field is static, anyway it shouldnot matter for thisquestion) along it's path and not through the surrounding substances and spaces? Do free electrons play the role of the electric field carriers along a conductor's path? If they are moving so slow, how do they pass electric field strength change so fast, if so?

How can then a plane fly up side down?

Great video! How come I'm only discovering your channel now?

Purpose of wire is a wave guide. Interesting.

Wow in under 5 minutes you have explained something that others couldn't in hours. Great job keep up the good work. 👍

Extremely helpful video and nicely explained

comming from veritasium's video, this helps alot

I can't guess his accent, i think it's German or slight British? (?

One question then why the higher density materials are around the centre of the earth not the surface of the earth?

That’s the most informative video I’ve seen in a long time

No you can't

Dude we r not stunt man, this thing happen in a one time in life so how we know when we have to jump ...we don't have machine that time so I can check how far m I?? Give some good solution those everyone CAN DO.....

I saw it happening many times but don't knew the science behind it. Thank you for this your channel really contains some of my childhood sily questions that I ashamed of asking someone 😐😅😅. Start your work again and follow some UA-cam SEO tips to increase traffic. I hope your channel grows soon. 💓

Sir please turn on the "Auto Generated English" caption please.

Hey Whoever you are, your channel contains many of my question that I am searching answer for many years.
