Minute 9:12, does the position of the Resistor matter? I mean given the flow direction, should the resistor be between the input and the LED lamp, so it will slow doen the current before it reaches to the lamp, or does it not matter? When not, how and why? Maybe someone wll explain, thank you!
Man did I luck out. I was on a little wikipedia-train going through articles on electricity, as my understanding isn't super great (physics was my worst class in high school). I came to youtube to look for 'how does a transformer work', found your video, and come to find this series of videos that is actively being uploaded (this specific video is a day old). Crazy luck.

@@MichaelJ44 Current always rises when the resistance drops which is why short circuit is so dangerous since there is no resistance. The higher the resistence the lower the current and the higher the voltage the higher the current's potential. It is a side effect basically of resistance and voltage.
mjchmara1 it looks like a typo. It should read: One Amp = One Coulomb per Second and 1 Coulomb = approx 6,000,000,000,000,000,000 electrons. Well spotted...
4:02 There's an error: in the video, you've said that you convert AC to DC using an inverter. That is wrong. You convert DC to AC using an inverter. AC to DC is converted using a rectifier.
This is a really good video series. I have a degree in Electrical Engineering and found practical things in them I did not know or fully understand. I hate to nitpick, but there is one concept with which I must take exception. That is the depiction of current as physical electrons racing through the conductor at tremendous speeds. It is the electromagnetic wave propagation that moves at incredibly high speeds of approximately 0.9c. In fact, the electrons merely "drift" at about 1mm/sec. I have not watched all of your videos, so I apologize if you have made this distinction elsewhere. Otherwise, keep up the good work.
Great work guys. I am studying for my physics test in electrodynamics and you guys managed to explain to me in 11 minutes what my teacher wasn't able to do in a week. Greeting from Croatia !
Dear Sir... very good videos. Thumbs up. A bit correction at minute 5:03. 1 Amp is not equal to 1 Coulomb. It is equal to 1 Coulomb per second. I = Q/t
Great video, but a few inaccuracies: E.g. "One Ampere is equal to one Coulomb" is an unfortunate way to put it - as Coulomb is charge, not current. It is claimed (in the same slide) that one Coulomb is equal to a certain number of electrons per second. No, that is current, not charge. This ought to be corrected, as is very basic and confusing for people who are learning electronics. An inverter converts DC to AC (4.04): The graphics is correct, but the commentary describes it as a rectifier, not an inverter.
Thank you for all your videos. I am an old Spanish student who was struggling to understand electricity in my engineering course and I can assure you that I understand a lot more with your English videos than with my Spanish lessons at school. Thanks a lot!..oh and...All the power!
4:02: "We can convert AC to DC using an inverter." Should be the other way round (as one can see on the screen): "We can convert DC to AC using an inverter."
This is the case when you consider Power (P) to be constant. Because P = V * I, if you increase voltage V, current I needs to decrease (for the same amount of power. For example, a 60W lamp designed to work with 240V will require half of the current than a 60W lamp designed to work with 120V. But, keep in mind that for THE SAME lamp, if you increase the applied voltage, its current will also increase (you will get more power).
Mohd Azmeer Well, that’s not strictly correct. From ohm’s law, increasing the voltage will increase the current and decreasing it will reduce the current and that’s the way to think about it. If it is a 120v circuit with a 60w lamp, increasing or decreasing the voltage will increase and decrease the current, just the same as the 240v circuit. However, for the same power, if the voltage is reduced then the current has to increase I = P/V A transformer is a good example of reducing or increasing the voltage. Say the voltage In is 240v in and 120v out. If the power in, equals the power out then P = Vin x In = Vout x Iout 60 = 240 x 0.25 = 120 x 0.5 So reducing the voltage, increases the current for the same power and increasing the voltage decreases the current for the same power. However, do not confuse this with ohm’s law. These are two completely separated circuits and ohm’s law will apply to both. Increase the voltage of Vin and In will increase. Increase the voltage of Vout and Iout will increase. Assume the transformer has a power factor of 1 and assume there are no losses.
Dude I've had only a vague understanding of what electrical current is for years... Just hearing an explanation that describes amps by the number of electrons per second makes *everything* make so much sense now.
*summary:* - electrical current is just electrons moving along a wire - voltage drives an electrical current - DC is when electrons flow in the same direction - AC is when they alternate their direction - you can use an inverter to convert AC to DC - make a resistor the weak point in your circuit to prevent other parts from burning out (these are called fuses)
Incorrect. A resistor and a fuse are very different. A resistor brings current and voltage to a specific point while a fuse is a safeguard that blows when the limit is reached.
@@Rexaurus Are you sure about this? Couldn't I just use an LED (which is a resistor - heats up in response to electron flow and as a result emits light) as a fuse? If I push too much current through my circuit, the LED will burn out, thus protecting the rest of my circuit. I don't really see what makes a fuse a fuse? Aren't they simply resistors internally?
Thanks a bunch. Seriously, I have an interview coming up as a solar tech, and need to brush up on my acdc electrical theory. Along with other sources I've used, this was a great help!
Great video, except for the ending. A circuit breaker exists to prevent fires, not to save your life from electrocution. I don’t want anyone to think that you can’t be hurt because a circuit breaker will save them.
I was arguing with my teacher about this. And he said that, technically it is true that the interrupter breaks the circuit due to an increase in current. It's just due to a ground fault instead of an overcurrent. But I would say that such a detail should be mentioned when talking to the audience of these kinds of videos.
@@jasisonee that part was unclear to me. Why touching the live wire will increase the current? Shouldn't the body add an extra resistance lowering the current?
Hi, he will have used Ohm's law. If you are not familiar with that law, it basically states the relationship between the current flowing between to points and the voltage across them. In short, the voltage across two points 'V' is equal to the product of the current 'I' and the resistance 'R' - so V = IR in short. It's worth memorising this if you can as you will use it all the time. In his example, the LED is rated at 25mA and has a forward voltage of 3.3v. If you are unfamiliar with that, just consider it the amount of voltage "used" by the LED to be in the "on" state. This leaves us with 5.7V of extra voltage to drop, as the battery is a 9V cell. So to compute how much resistance is required to limit the current to 25mA, we can just re-arrange the law in the form R = V/I, where V is our voltage (5.7V) and I is our current (25mA, so 0.025A). If you calculate this value you will get a resistance of 228 ohms, as the minimum resistance required. If you are wondering why the video man selected 270ohms, it is likely because it's the closest standard resistor size to 228 without going to anything smaller. You normally want to play it safe like this because resistors are only guarenteed to be within a certain tolerance of their stated value. I hope that helps.
A typical LED is lighting normally at 20mA for for a 5V supply, the limiting resistor is found by dividing 5000 mV by 20 mA giving 250 ohms. So a 270 ohm resistor will do just fine. Using a lower resistance the LED might be too bright and even burn out, a higher resistor gives a dimmer light.
You hurt me. I red your reply and exclaimed out loud... in pain! That is no joke. I really did. What is "education" doing to us? Relieving us of thousands of pounds/dollars, and still requiring us to go on to TH-cam to actually learn stuff? What do we pay for, exactly? (I know "red" is not spelled correctly. That is to avoid "reed".) I feel your pain, man. So sorry.

1 ampere means 1 coulomb per second? Right? Or 1 amp means only 1 coulomb? Coulomb is not synonymous of ampere? Coulomb per second is ampere. Right? Sorry if this is a bad question.
It is a mistake in the video. 1A=1C/1s or in differential form: I=dq/dt q-electric charge (measured in Coulombs) t-time (seconds) Many also use As (Amp*second) instead of Coulomb.
Thanks a lot for this video!!! People have been wanting to figure out how to get more voltage out of a solar cell or battery. Well that can't actually be done, but we can make them appear like they are providing more voltage using a current amplifier added. It is similar to how capacitors appear to pass AC electricity, but actually they don't. I drew two schematic diagrams and will get back to you on this idea of mine after testing it. If successful, a 6 volt battery will do what a 12 volt battery can do! 💯💰🙏
My experiment was a success saving as much as 61.9% current when applying 7.53 volts (from a variable DC Power Supply) to a 12 volt DC automotive bulb. Capacitance maximum value changes each time the input voltage changes and also maybe the total impedance of the load device connected to the input source.
3 ampéres = 1,8726x10^19 electróes/segundo e não 1,93x10^19.OK?! Espero que me diga se estou certo ou estou errado. Muito obrigado. Abraço de Portugal.
Case1: If we place 2 resistor in parallel of same value.(1k0hm) Case2: If we place place 3 resistor of same value.(1kohm). Which case draws more current from battery.
when explaining OHMS, the diagram at 8:00, would the meter calculate 1.5 for the branch after lamp A, because electrons already are being split going towards lamp A, while making its why towards lamp B?
These videos are fantastic. They help pull back the veil on electical science that to this point has remained a vague mystery to me, starting with why doesn't electricity leak out of the living room wall socket? Now things make sense. But question: isn't large scale long distance electrical transmission performed using DC?
I've watched your videos on testing AA batteries - great stuff. You suggest using a 100 ohm resistor with a multimeter; but I find there are 1/4w and 1/2w resistors. Does it make any difference which resistor I use?
Great video series! One question thought, you mention that you can change the spot you connect the multimeter and still get the same amp reading. Now I'm wondering, don't the cables need to be switched around for this? The black cable is the negative, red positive, right? So when the multimeter is connected at the top, it is connected in this order, but when its moved down, the red comes first, connecting the positive cable to the negative side of the battery, and black to positive, which would be wrong? or am I missing something? 6:38 onwards is where this occurs

My experiment was a success saving as much as 61.9% current when applying 7.53 volts (from a variable DC Power Supply) to a 12 volt DC automotive bulb. Capacitance maximum value changes each time the input voltage changes and also maybe the total impedance of the load device connected to the input source.

in your LED example at 9:13 how can you calculate the current of the circuit using ohms law?
Do you have to factor in the resistance of the LED?

3 ampéres = 1,8726x10^19 electróes/segundo e não 1,93x10^19.OK?!
Espero que me diga se estou certo ou estou errado.
Muito obrigado. Abraço de Portugal.
Case1: If we place 2 resistor in parallel of same value.(1k0hm)
Case2: If we place place 3 resistor of same value.(1kohm).
Which case draws more current from battery.
Sure!
Mufakkir Hussain did you figured it out? If yes, what is the answer? Thanks
@@mufakkirhussain2816 Case 2 if the resistors are placed in parallel

thx for the info for the current
i love these plumbing analogies, thinking about electricity as water makes it very easy to understand.
You make elecrtricity more simple to understand thank you

when explaining OHMS, the diagram at 8:00, would the meter calculate 1.5 for the branch after lamp A, because electrons already are being split going towards lamp A, while making its why towards lamp B?
brilliant I am learning a lot
This was really helpful thx!!
Watch new new version, much better th-cam.com/video/kcL2_D33k3o/w-d-xo.html
you probably saved my life with your videos.
ALL THE POWER!
Thank you sir for making basic electrical engineering so easy to understand
Thank you very much!
The best of the best!
These videos are fantastic. They help pull back the veil on electical science that to this point has remained a vague mystery to me, starting with why doesn't electricity leak out of the living room wall socket? Now things make sense.
But question: isn't large scale long distance electrical transmission performed using DC?

well, sometimes. AC is still used more widely though since it's easier to step up/down

Hi! Love your videos! Can you make a video on inrush current ?
Thanks for explaining
Awesome videos none the less!
I've watched your videos on testing AA batteries - great stuff. You suggest using a 100 ohm resistor with a multimeter; but I find there are 1/4w and 1/2w resistors. Does it make any difference which resistor I use?
Great video series! One question thought, you mention that you can change the spot you connect the multimeter and still get the same amp reading. Now I'm wondering, don't the cables need to be switched around for this? The black cable is the negative, red positive, right? So when the multimeter is connected at the top, it is connected in this order, but when its moved down, the red comes first, connecting the positive cable to the negative side of the battery, and black to positive, which would be wrong? or am I missing something? 6:38 onwards is where this occurs
