   extremely good video. glad i found it lol

   The water analogy has always bothered me – as soon as you open a valve water pressure will start to drop and the water level will drop at a constant(ish) rate. This isn’t true of batteries – the voltage drops according to a curve. For Li ion batteries it hardly drops between 80 -20% state of charge and then drops rapidly towards the end. So would a more realistic depiction be to have a second storage tank feeding the first one to keep its water level fairly constant (depending on the exit flow rate / current) until that one empties? If that’s not the case, please help me understand what is going on.

   Is. 220 volts twice as dangerous as 110 volts?

   Taiwan uses 110V, just like its father and mother, Japan and USA.

   Can you show me how many volts ⚡a copper wire can hold and show me how thick it would need to be. To safely hold a high level of electricity

   The core meaning of Voltage is not yet explained, though. By that I mean voltage is the pressure that force electrons to follow their wanted path, toward elements direction through wire. Low voltage will result in electrons flow arbitrary between atoms without any meaningful direction. The speed of electrons is always c, light speed. But, the direction is mainly affected by voltage or the pressure!

    Bruh I have a test in a few hours and probably only get 4 hours of sleep fuck me I have to relearn all of the lessons I have bruhhh

    Uruguay uses 220V 50Hz.

    The device doesn’t ‘need’ 1A that’s what it draws, it’s not having 1A ‘pumped’ into it, that’s confusing, and showing electron flow rather than conventional current is confusing.

    Thank you!! It helped me a lot.
    I have learned my electricity chapters but once I think about potential difference or voltage. My all concept become confusing this video helped me alot

    The battery at 2:50 seems to be running from negative to positive. Is this a mistake in the video?

    Thank you for this. I struggle with these concepts but now I’m starting to get it, especially series vs parallel.

    At 2:40 you have a 1.5 V battery. Assuming you start with a brand new battery, what is the voltage at the negative end and the positive end when:
    1. You initially start
    2. The battery is partially depleted
    3. When the battery no longer works

    If I put the batteries in parallel that means I have 1.5 V but 2x the current of a battery?!

    
    
    
40. Chum on May 20, 2022 at 9:56 am

    So, if those two bulbs were in parallel, they’d use 1.5V each? Instead of it being split by half?

    Just want to mention there is a spelling mistake around 1min20 into this video. Says: Water analyogy*, I think it should be spelt "water analogy". Some really good content on this channel.

    There are actually more spelling mistakes in the video but, it would be silly to even bring it up

    I remember when I was in 7th grade I connected a 1.5V LED to a 220V power source and after that me and my friends were in the principal’s office.

    
    
    
46. Errol Burden on May 20, 2022 at 10:00 am

    Why do all the explanations of electric current state that electrons flow or travel? Which is not true. I think that fundamentally leaves everyone confused as to how electricity actually works.

    I didn’t get the voltage of the alternative current 🙁

49. AwestruckChemicals on May 20, 2022 at 10:02 am

    But my question is, what makes one battery 1.5V and another 9V? I mean, what physically is creating that difference?

    6:29 it is 12.5 ×10^17 electrons(0.2C)
