you are awesome. ... thanks man!

[thenerfwarriors1]

why do you have 3 computers?

[HereIsTheRevolution]

@thenerfwarriors1 he has to his desktop is dual screened and the other one is a laptop

great job

[Madcow800]

before i started watching your video i tried to make a resistor slow down the speed of a motor i had well the motor wouldnt work at all so i kept adding more voltage thinking that the resistor was too strong and my resistor caught fire and the motor still didnt work!

[TheIrock111]

@Madcow800, Why on earth did u increase the voltage? That will increase the power and fry the circuit.

[merlinchanelle]

thank man your cool

[debater96]

What are some times that you would use a resistor for? Is it like when you have a battery that gives 9V but the component only need 6V to function? Is that when you would use a resistor?

This stuff is great. Thanks for making the videos and your a brilliant teacher explaining everything so clearly. I just subscribed. Thanks dude

[Endless37O]

Im puting Leds in my speakers in my car but i dont noe which Resistors should i get 1/2w or sumthing esle ??.because wen ever i turn the music loud the leds dies.

[OCDADVENTURES101]

can i use a resistor to lower 4.5V to 2.2V?

[FrancekPirosrancek]

@OCDADVENTURES101 yes but then you need 2 sam ones and you are gonna have 2x 2,25V and then everything that is parallel to either of resistors will have 2,25V. Sry for the late response.

[azntony619]

awesome videos, can you tell me where to get these parts, other than ebay or amazon?

[MrUnknown757]

these videos are really good

your v. good at explaing and talking about

this. keep it up

God Bless

The difference between 1/2 and 1/4 Watt resistors is their ability to carry current and withstand/dissipate heat as curent passes throughthem.

Surface mount refers to the method of soldering them to a board.

Beginners should use the through hole mounting which requires wires.

i love you vids,

i always watch it ;)

you great with explaining

thx!!

[Zuntyh]

Nice to see you are taking a total beginner approach set of tutorials. I'll be awaiting the later ones though, considering this stuff is like standard grade physics.

I actually have a few robots that I used to build when I was a child from a magazine, but I never got a few components, hopefully after watching the end of your tutorial and my increased knowledge of electronics I can fix it up ^^.

Good video. You might want to go over the color bands and how they can be used to identify overall resistance and tolerance - or at least mention it. As far as tolerance bands, you want to look for a gold band (which indicates 5% tolerance). Silver is 10% and no band is 20%.

btw - the tolerance is total tolerance, not +/-. So a 5% tolerance on a 100 ohm resistor is actually 97.5 to 102.5 ohms.

Cheers. Keep em coming.

[thenewboston]

thanks man im uploading 2 more videos on resistors now, one on how to test using a multimeter and one on how to use the color bands
