The Learning Circuit – Resistors

The Learning Circuit - Resistors

Karen explains what resistors are, how resistors are represented on a schematic, various types of resistors, and the characteristics of those resistors. She’ll go over carbon composite resistors, thin film resistors such as carbon, metal, and metal oxide film; thick film or cermet resistors; wire round resistors; variable resistors such as thermistors, potentiometers, and photo or LDR resistors; SMD resistors; trimmer pots; and more.

According to Ohm’s Law, in every circuit there is a balance between voltage, current, and resistance. Most electrical components require a certain voltage and current to function properly. By adding resistors, you can control the voltage and current in various parts of a circuit. Resistance in an electrical circuit is when a material prevents some or all of the...

    I didn't get this much information on resistors in the electronics course I took.
    Great video Karen.

    Hi Karen, good to see you and Felix are still going to be on here.

    I love it when you talk science to me…

    No really, I’m much smarter after watching this! 🙂

    I like these learning circuit videos, because while most I the topics I already understand they serve as a refresher and often cover details I'm not aware of (like resistor series). And who hasn't cooked a resistor and let out the magic smoke at least once? ProTip: turn on your bench supply before connecting your circuit so you can adjust it without sending 12V 3A across a tiny resistor.????

    What kind of variable resistor control with code using gpio pins?

    Safe to say a lot of us are in love with you, Karen. Good luck with all the changes n stuff. Cheers.

    Superconductors don't have resistance, but as of now, it's unlikely you'll just come across one. 🙂

    Very useful video. Have you moved shops now Ben has left, I assume that Ben owned the original shop in your recent videos.

    Where can I find posters like the one in the background and others with helpful reminders that I can put up in a shop?

    You forgot to mention potentiometers come in linear and tapered, and you can parallel up low wattage resistors for higher current handling

    Thanks Karen. Looking forward to capacitors and inductors…Already missing the Ben Heck Show but this series looks great..

    I've worked with resistors before, but never really looked into the institutional knowledge and expanded data information you presented here. Thank you Karen!?

    First they followed us into gaming servers. Now they're talking about electronics? Whats next? Damn skirts. The society is heading for a collapse

    Karen, great video and as always, I love your shirt. ? In all seriousness I look forward to your videos. You do an excellant job of explaining things.

    Looking forward to a transistor video or two. I assume capacitors and coils will come before that.

    The thing i really like about these videos is unlike many other tutorials they are trying to teach the basics to newcomers unlike many other tutorials that assume you already know the basics .
    I didn't watch this presentation because i needed to learn about resistors – i have been an Electronics enthusiast for over 40 years and know what i need to know – instead i watched it anyhow and supported it because i feel it is important to do so as the channel is helping newcomers to the field of electronics .
    Keep up the fantastic work you do Karen !

    Aww.. thanks Karen. I always thought rheostat was just an obsolete word for potentiometer.
