Very nice lesson. Easy to understand and nicely put together :D Bravo!
6:10 You said 'the colour band is grey' but highlighted the green band on the table. I think it would be better if you put a caption for correction because I see many people bewildered by the contents of the video. Other than that, pretty well explained. Great job

Lovely video content! Apologies for the intrusion, I would appreciate your thoughts. Have you considered - Qanayce Wiyulian Equalizer (Have a quick look on google can't remember the place now)? It is a good one off product for unveiling the technique to repair your electronic items without the hard work. Ive heard some interesting things about it and my work buddy after many years got excellent results with it.

You should include the voltage drop across the LED when calculating the resistance required to produce 30mA. Typically, red LEDs operate at 2V. So the calculation should be (9V - 2V)/0.03 = 230 ohms. However, with 300 ohms, the current will be 23mA, which is better than 30mA, because you should never operate any device at its rated maximum.

I'm glad you explained how resistance affects the "LID" ;)
This version of the essential resistor was designed and developed in 1959 by Chicago inventor, Otis Boykin. Mr. Boykin would later become better known for his next invention, a control unit for the pacemaker, which used electrical impulses to stimulate the heart and create a steady heartbeat.
Sir really good .Very clear voice easy to understand. Thanks
thanks, very interactive and clear 👍
Thanks!! Nice Explanation
Thank you for making it understandable for someone like me with no knowledge of electronics.

Hi there
well explained man... great work.. keep it up.
Excellent video! Thank you so much!
Great video; however, I see two mistakes right away. 1st one is the LED itself, its hooked up backwards, shorter leg is usually/normally always negative. The 2nd mistake is that he chose the wrong value of the resistor's Multiplier, even though he did say the right one (he chose green instead of gray).

@Brian, I am starting my first project. I need someone with knowledge to review my project contents and recommend missing/needed resistors, etc to complete my project to fully function able in all areas. Can I resource you? I have a handicap that limits the way/method I obtain knowledge. Hence the “first” time, I need guidance/ assistance. I am determined not only to complete this project… but obtain. Skills to complete a total of 250 projects on my own….later on. Most Humble Appreciation! Alton

Hi there
thanks this was help full for my casp report
The LED part is inaccurate, since you didn't take into account the voltage drop on the LED. A 3mm red LED has about 1.7V drop across it, so the drop on the resistor is about 7.3V. The correct equation is R=7.3V/30mA, so R=243.333Ω

At the 2:28 mark you converted the mille amp ( 1/1000th ) of 30 to 0.03 to give 9/0.03 . Others may not have caught that if they were just checking the tutorial out.

Does resistor delays power consumption? i had a case of smoke generator that i mdel a coil out of vape wire and a 5v fan and the power was 7.5volt 1000mah rechargeable battery, it runs for roughly 8 -10 minute and the power will ran out, one of the biggest reason i'm thinking on adding a resistor was i hope it would slow down the flow of the current but does this actually means same amount of power would still be wasted ? and that protects the fans and the heater wire coil from burn out?, i'm working on my second homemade smoke generator for my RC(remote control) tiger 1 1:16 , but this time the boiling chamber was much more compact and smaller which made the smoke liquid runs out even faster and the coil would caught lit up with fire and later extinguish itself when the oxygen in the bottle was used up, i still had a lot of adjustment to do with this smoke generator , improved until it was much more feasible to use than conventional aftermarket smoke generator.
great explanation thank you
good video.... i came to know about resistors.. thanks a lot
Thanks for clearing my doubt.
Amazing, thanks!
very clear explanation.
Hi, when a current enters the resistor does it decrease the amount of electrons and we get less electrons comes out of resistor (at the other end) OR it (resistor) decreases the speed of electrons and we get slower electrons coming out from the other end of the resistor? Also when we say that 2A is going through resister R , does that mean before entering the resister or after the resister? Please help
thank you for your information.
would you please tell me if you know that in the 6 minute and 9 seconds you; it seems make the grey band calculate with a green value .....if this is so then you may want to indicate a correction and give the video the high standard you have with the rest of it , for the sake of those who are less able to deal with errors in their self educating. I appreciate the hard work you all put into the priceless videos on youtube in this field. thanks john
Yes, when you connect two or more resistors in series in a ckt, (i.e R1 & next to it, R2, R3), each resistor values (ohms) "R" are added, as to find Equivalent Resistance Requ= R1+2+R3, while calculating the current flow I=V/(R1+R2+R3)=V/Requ. The reason is , the voltage potential at the first resistor arriving at the resistor R1 is taken as Voltage for calculating current flow on each resistors in series. Hence, the current flows on all the resistors will be the same, but with drop in voltage.

No I don't think that is correct. By ohm's law: V=(A)(R) The higher the resistance, if the amperage stayed the same, voltage would also rise proportionally; obviously, that is NOT what happens, resistors do not add voltage. If the voltage stays the same (given a potential differential = X from a given source like a battery) and if we change the value of the resistor, then what must change is the current to make the numbers add up: V=10 R=10 , 100 , 1000 A=X 1. 10=(x)(10) A=1 2. 10=(x)(100) A=0.1 3. 10=(x)(1000) A=0.01 The higher the resistance = the LOWER THE CURRENT.
thats a great explanation..
Wow this helped me soooo much!!! Thanks alot! :D :)
awesome video.
Thank u guys for helping me
This is amazing. I have a question though. why does a resistor have to be on the positive lead? I understand that the assumption of the current direction ( from +ve to -ve ) was a mistake bcuz scientists when they were first working with electricity, they didn't know about the structure of an atom. Shouldn't we adopt the correct direction then to prevent the LED from burning out? which is from -ve to +ve? (Thank you in advance for any help you might be able to provide)

Excellent video. I learned a lot. I am 67.
if you take the example of a hydraulic pipe then when the flow of the water is resisted hence creating pressure and the same happens with resistors then shouldn't the voltage shoot up in relation with the flow of electrons? just like when you press the tube of a vinyl pipe when water is flowing through it?
Sharing information and thank you
Thank you for the excellent video !!!! Ken
Great vid, thanks for sharing. Do you know where I can find an electrical board hr51a? It is used for charging an 18v. There is only 4 parts on this board, 3 are resisters I don't know what the other part s is. It is a cylinder shape thing with 3 loops around it . Two brown and one black. Thanks

The real Ohms law-> kzread.info/dash/bejne/eZdl2bidkrmvYKg.html
Nice vid dude thx!
really thankfull, I confused in register and resistor
So does the resistor change its Ohms if connected to something else ? Like, using that same as in the LED example, with another 45mA LED, will that same resistor switch to 200 Om ? Or is that value a constant depending on what ? The material that resistor is built with ? Can that same transistor be used for some high voltage stuff like city electrical connections with 1.000.000 V ? If no why not ?
Thank you so much!!
I got a little light-headed trying to absorb all that. Actually for a guy as dumb as me, it made good sense. I now have a basic understanding of what resistors are. Thanks.
wow.. thank you for this
Theres something wrong in this video but we can adjust for simple error ...make sure to be more strict in posting video to help more newbies but u explain well about the topic sir god bless and more power...
good guide
nice video
thanx for the information but can any one say that in the video it was shown that by connecting the resistor in series with bulb the current was controlled but in case of theory we use to say that for series connection of resistors the current flowing is same at all the resisters connected in series what does it mean?
Very helpful
