  • 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.

  • 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

  • how are we going to put the robot together like when you said in the first tutorial

  • 2009?!!! And you're still making tutorials in 2012!!! Hmmm... Wow

  • He looks a bit like Shia LaBeouf out of Transformers

  • you are awesome. ... thanks man!

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

  • why do you have 3 computers?

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

  • great job

  • 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!

  • 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?
