    how a light bulb can "draw" something? in this case current (electrons per second)? a higher wattage light bulb has a filament with a lower electrical
    resistance? edit: 2:26 —> why through the light bulb flows fewer amps at a higher voltage than the led setup which has a lower difference in potential energy but through which flows more amperes?

    I think you need clearer explanation for the 120V AC (I believe this is RMS voltage) driving light bulb compared to LED requiring DC.

    I have a question
    If we are using 60watt bulb in 220v then amphere is very low but the normal home wire electricity will give more than that how the bulb work in high amphere

    why and the heck don’t they just use one word for one thing amps, current. I, Joules, combabiyas… what the… to damn confusing..

    I have a question.
    On 3:24
    So the power converted into heat on the resistor is called heat dissipation?

    How do we calculate the power converted into heat & light in the light bulb? Do we use 3 Volts in the equation?

    Question: Can a person who has ZERO ground in a house, ground just ONE power outlet in the house by running a ground wire from the ground terminal out into a grounded stake in the ground? My house has old screw in fuses, and absolutely no ground wire anywhere. There’s no plumbing or anything in the house to use for a ground either. I run a compost toilet/outhouse, and haul water there. I want to avoid the risk of frying my electronics but I cannot afford a full electrical update. It’s 10,000-12,000 to do this (almost as much as I PAID for the house!!)… I won’t be able to afford it for YEARS best case. SO what I want to do, is somehow protect my electronics by at least grounding ONE outlet cheaply. Is this possible? AND NO, I DO NOT HAVE INSURANCE, so I don’t care if things are certified insurable, just so long as my gear is safe.

    How much time electrons takes to transfer the energy, as you have said increasing voltage will increase the transferred energy, i think its speed of light at which energy is transferred.

    I like how you encourage the viewers to build stuff from the beginning. Not just theories, like school bullshit.

    This might be a stupid question but I’ll ask it anyway…

    Why won’t electrons flow the opposite way if connecting the battery the wrong way, ending in the same result?
