    Excellent videos! I’m a big fan. Some of us watching these are not guys though. 😉



  2. Mohamed EL-SHAMY on February 10, 2020 at 9:43 pm

    Which reference do u recommend to get such knowledge about electricity?



  3. Max Clakr on February 10, 2020 at 9:45 pm

    If one amp is one coulomb, why measure currents in amps? Why not just measure in coulombs?



  4. The PineApple on February 10, 2020 at 9:46 pm

    In a 10 minute video you elegantly sum up 6 weeks of teaching in a first year engineering paper



  5. Mathew Ostovich on February 10, 2020 at 9:48 pm

    Sulfer free gold is very inert material. White gold.useless for audio.



  6. NoisyBadAss on February 10, 2020 at 9:51 pm

    I just found your channel and already subscribed. Coffee coins sent and thank you for your time and effort Sir to teaching us. Keep up the good work. ☝🏻☺️✌🏻



  7. Raj on February 10, 2020 at 9:54 pm

    And how do we generate the magnetic field around coil to induce current



  8. Temesgen Hagos on February 10, 2020 at 9:55 pm

    Amazing explanation



  9. Honey da Pizzainator on February 10, 2020 at 9:57 pm

    Teacher: *explains this and doesnt manage to make me understand anything in 4 years worth of time*
    Me: watches these videos and understands triple the amount of stuff
    Teacher: "You werent supposed to do that"



  10. Justice Hussein on February 10, 2020 at 9:58 pm

    Thank you very much.

    Why don’t you get a shock from the negative in an ac circuit?!



  13. Sabit Ullah on February 10, 2020 at 10:02 pm

    Please make a video about "What is Resistance?"
    Please 🙏
    Or please provide me a source from where I can learn about Resistance 🙏



  14. Waldemar Ożóg on February 10, 2020 at 10:03 pm

    Were neutrino?? Is elektron a 2 fotons??



  15. That inventor 2:01 on February 10, 2020 at 10:05 pm

    I’m glad I found this at 14 instead of 40



  16. Hiren Patel on February 10, 2020 at 10:07 pm

    Thanks you. Please do a vid on mosfet and diodes and how those work. Thanks in advance.



  17. Ron Quin on February 10, 2020 at 10:07 pm

    It is the flow of charge that really does the work. The flow of electrons is very slow. All in all I really have using hydro dynamic as analogy



  18. Trends Now! on February 10, 2020 at 10:09 pm

    Why everyone is being humourous in this serious educational video😢😢



  19. TheGuy on February 10, 2020 at 10:10 pm

    Why cant we keep an led running forever if the power goes back into the battery is it lost as heat when the bulbs are warm? Also is hz on a household appliance example 120v 60hz the frequency in which the magnets move side to side like the frequency in which the current flips??? Have to admit never really thought how interesting electicity is



  20. Turtle Squirt on February 10, 2020 at 10:13 pm

    Orbital shells arent flight paths, they are fundamentally just probability rings of where to locate an electron in the "cloud" only after measured 1:05



  21. Prasath V on February 10, 2020 at 10:14 pm

    hello sir there is any autocad tutorial from yours



  22. Hillside AnimalYT on February 10, 2020 at 10:16 pm

    Good stuff very clear and useful



  23. ComProgExpert on February 10, 2020 at 10:17 pm

    Great…



  24. Spinks on February 10, 2020 at 10:17 pm

    we haven’t even began…but we’d have mix the Elements…its actually negative referenced voltage that scaresss me…this stuff excites atoms and electrons. we’d be able to create massive power but you’d have atoms moving at high velocity and thats not good thats where nuclear stuff can happen fission/fusion.



  25. Mathew Ostovich on February 10, 2020 at 10:18 pm

    Resistors can also be used to creat an illusion of higher ohm counts.



  26. Ivan Meouch on February 10, 2020 at 10:18 pm

    I’m pretty sure it should say 1 Amp = 1 Coulomb *Per second*
    And 1 Coulomb is simply the charge, not per second



  27. 오빤전기쟁이 on February 10, 2020 at 10:21 pm

    Nice video ^^
    천천히 구경하고갈께요



  28. Mathew Ostovich on February 10, 2020 at 10:21 pm

    Gold is powerful because the sulfur content pushes the electrons and ads momentum through the use of free moving electrons that have better continuity.



  29. Lambder on February 10, 2020 at 10:23 pm

    4:09 You explained correctly the definition of Amps but the image shows different 😀



  30. James Solomon on February 10, 2020 at 10:24 pm

    Bro lost me at protons neutrons



  31. Jovet on February 10, 2020 at 10:24 pm

    3:49 I winced at the "LED Light Bulb" bit.



  32. Baker Mclendon on February 10, 2020 at 10:26 pm

    @ 1:24. Shouldn’t the number of neutrons be 34? The atomic number is 29. The mass is 63.



  33. Sam Hobbs on February 10, 2020 at 10:29 pm

    So you’re telling me that if we just have a very large coil of copper wire and strong magnetic, we can generate electrical current to power stuff???



  34. Mr. Grey Sky on February 10, 2020 at 10:29 pm

    It blew my mind when I found out that electrons flow from the negative terminal 😮



  35. Mathew Ostovich on February 10, 2020 at 10:30 pm

    Vibration not flow



  36. Nathaniel Cushman on February 10, 2020 at 10:31 pm

    Why was wattage not mentioned?



  37. Вася on February 10, 2020 at 10:31 pm

    Im sure this would be easier to understand if i havent smoked pot past 15 years



  38. James A on February 10, 2020 at 10:32 pm

    ALL “The Engineering Mindset “ videos are super easy to help teach and bring understanding! 
    I recommend subscription to anyone who wants to expand knowledge.



  39. Somagarn Yo on February 10, 2020 at 10:34 pm

    @1.09 Electron travel at less than 1% of the speed of light not almost the speed of light as stated.



  40. Radin Z on February 10, 2020 at 10:34 pm

    my 8 year old brain rn
    i just wished that coulombs had 700000000000000 more electrons per second😏



  41. Shahid Mian on February 10, 2020 at 10:35 pm

    Alas! I should have watch it earlier 😭



  42. Mathew Ostovich on February 10, 2020 at 10:36 pm

    Physics claims that electrons flow in both directions at the same time.



  43. Clit Commander on February 10, 2020 at 10:36 pm

    Someone answer me! Do electricians make alot of money?! By alot i mean can i buy a house and have a GT-R and a corvette?!



  44. Chris Golding on February 10, 2020 at 10:37 pm

    Wow your videos are amazing really explained thoroughly for everyone thankyou I’m definitely subscribing =)



  45. Abdullah Aghazadah on February 10, 2020 at 10:37 pm

    *summary:*
    – the electrons in the valence shell (outter shell) of some atoms can flow from one atom to a neighboring one
    – if you create an *electric potential* (aka *voltage*) difference across a *conducting* wire, the electrons will flow in one direction through that wire
    – if you cut out a small piece of the conducting wire, and replace it with a *resisting* wire, the resisting wire will get hot as electrons flow through it
    – you can use this concept to create things live electric stoves, heaters, etc
    – there are certain resisting material, that when heated up, will produce a lot of bright light, you can use this to create electric light bulbs

    *units:*
    – *voltage* is a measure of electric potential difference between 2 points in a conducting wire
    – the unit of voltage is *Volt*
    – a Volt is the number of joules of energy given of as 1 coulomb of electrons flows from one point to the other
    – a *coulomb* is just a really large number
    – *current* is a measure of how many electrons are flowing through the wire per second
    – the unit for current is *Amps*
    – 1 Amp is 1 coulomb of electrons lowing past a certain point in your wire per second

    *briefly covered stuff:*
    – an *inducer* is a coil of wire, that generates a magnetic field in response to current going through the wire
    – the magnetic field creates a voltage in the opposite direction as the current
    – this is how AC (alternating current) is produce
    – *AC* is when you move electrons in one direction in the wire, then in the opposite direction, then in the original direction, then in the opposite, and repeat
    – *DC* (direct current) is when electrons move in the same direction the whole time
    – a *capacitor* builds up charges as current flows through it (when current stops flowing, the charge dissipates)

    Thanks for this video! Extremely well made!



  46. Mathew Ostovich on February 10, 2020 at 10:37 pm

    This is simple. Internal combustion motors are essentially electric air pumps with petroleum used as a motivating force.



  47. Lee Pearce on February 10, 2020 at 10:39 pm

    Great video thank you very much. Just a few things that don’t understand but I don’t know anything about electricity anyway. Thank you great video.



  48. andrew paul on February 10, 2020 at 10:39 pm

    This is cute but as we all know by now there are really 4 poles that make up electricity!



  49. Aniruddh sawant on February 10, 2020 at 10:40 pm

    Hi, your videos helped a lot ! Many Thanks !!, is it possible to touchbase on topics of switchgears, circuitbreakers, busbars..? your explanation for sure will clear all our basic doubts 🙂
