Damn you guys went hard on resistor basics! Four years of electrical engineering and the E-series was never explicitly explained to me before... lol Nice to finally have that sorted.
Justin Lee - Isn't it annoying that no matter how high the cost of education becomes, you have to wait for a free UA-cam video to give you the information that should have been included in the course?
You prolly dont give a shit but does someone know a way to log back into an Instagram account? I stupidly lost the account password. I appreciate any tips you can give me.
@Seth Noah I really appreciate your reply. I got to the site through google and im waiting for the hacking stuff atm. I see it takes a while so I will reply here later with my results.
YAY! I used to watch Ben Heck but then UA-cam stopped sending me videos and I kinda forgot >.< This was in my feed! Glad to see you're still doing awesome work!
I've worked with resistors before, but never really looked into the institutional knowledge and expanded data information you presented here. Thank you Karen!😊
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.🔌⚡🔥💨
Memory effect in resistors, motor coils, capacitors, and other components. The trick to remove the memory effect is, to overload the device then it becomes industrial, so you can use it for high performance use. Motors have to be offloaded, then the collectors have to be cleaned, the memory effect is in the brushed surface. By starting it 20x, it will spin up, and can be used as an industrial device. Solar panels are also memory effected when bought, and needs a full season to make it become industrial.
Wow Karen that was a great video loads of work for u as a presenter in that one. Packed with info and really well presented its nice to see u taking a bigger role hope it continues! Well done.
Soooo glad I ran across this. The video explained some things I just never gave much thought to. GREAT, Very useful information. The little FedEx guy on the shelf was a bit distracting though.
Great video. I NEED to learn more of the basics. I would love to see you guys use a 555 timer to make a "rapid fire" button for a controller, or possibly a strobe light.
I've made one for a wired 360 controller, But I'd like to know how the parts work. How to adjust speed , etc. I just copied what I saw in a video that had no other info. I know you shouldn't use them online, but I rarely if ever play online. The button is great fun on COD or Left for Dead 2, etc. Have a good one Dude.
Any idea how I can tell if my resistors are Metal film, or Carbon film? I just got a truckload of various NOS resistors, and almost all of them are the smooth/shiny looking lighter beige (or whatever you wanna call it), but no coloured ones. I'm just curious, because I noticed that it looks like they make the lighter looking one's in MF, and CF, so just curious if anyone knows how I could find out. Cheers.They all look exactly like the one's at 2:19 and 2:24 pretty much.
I wonder if you may have a voltage regulator circuit suitable for a motorcycle voltage of 20v ac to regulate at around 13.5 v to charge a battery and regulate current to supply ancillary equipment lights etc
Can you please make a video about smd inductors and how to read the value? I want to replace some inductor on my laptop board..I can't find anything on internet...R68322RQH this is the inductor
I love your videos they are great my aunt used to work at Hewlett-Packard I used to get bags of resistors transistors capacitors lot of them gold plated boy if save them back then they would have been worth some money I had a lot of fun building circuits of fun building circuits
1:47 *NO!!! NOT more efficiency!!* Carbon composition resistors were replaced because they had poor tolerances, due to the value drifting due to moisture and temperature, as well as higher noise. Carbon film and metal film resistors are superior because they eliminate these problems. Metal films also have the better temperature coefficients (which can be precisely controlled with the metal alloy used) Other than that, good video. :)
Suggestion for Demonstration of WHY Wattage Rating of Resistors matter: Take a 0.25 Watt 1 Ohm Carbon Resistor and a 8 Volt Battery. Do the Calculations to get that RV**2 = 1*9*9 = 81 Watts > 0.25 Watts, i.e. 0 Volts will fry that Resister with some Overkill. Proceed with this experiment with the usual "Do Not Try This At Home" Warning. Hook it up and Go Snap, Crackle, Pop!

Thanks Karen! Brings me back to my old physics labs during freshman year of college. Nice to see more women in the field. You're amazing!
I didn't get this much information on resistors in the electronics course I took.
Great video Karen.

@Seth Noah it did the trick and I now got access to my account again. I'm so happy!
Thank you so much, you really help me out :D
@Jonas Johnathan no problem xD
Hi Karen, good to see you and Felix are still going to be on here.
Hi! Thanks! It's good to still be here. :D

I wish we had that type of teaching videos available back in the seventies.
Alex Abadi I agree, we the new generation are very much blessed with the internet

Thanks! It's great to see people appreciate all the effort I put in. I love spreading knowledge and want to get more people excited about making!
Miss Karen, thank you, As this gesture of sharing well gained knowledge is equally as a well shared gesture, Godspeed
Thanks Karen. Looking forward to capacitors and inductors...Already missing the Ben Heck Show but this series looks great..
Soooo glad I ran across this. The video explained some things I just never gave much thought to. GREAT, Very useful information. The little FedEx guy on the shelf was a bit distracting though.
you give the best presentation about anything
Great video. I NEED to learn more of the basics. I would love to see you guys use a 555 timer to make a "rapid fire" button for a controller, or possibly a strobe light.
Brad Young hmmmm... that could make a video...

I've got 555 timers on the list of subjects to cover in the future. Happy to take suggestions for the corresponding project video!
Thank you so much. You are a great teacher. I watch all your videos ☺️.
Thank you! 😃 You should check out the new series: DC to Daylight!
I have a question I know a resistors in series can be a voltage divider but, what's the application of a resistors in parallel. Thanks
Excellent Video Karen...
Safe to say a lot of us are in love with you, Karen. Good luck with all the changes n stuff. Cheers.
yeah im sure alot of are in love with karen
Great video. I now understand that resistance is not useless.
Ah, this looks like excellent series
Fantastic comprehensive reference & overview of resistors Karen, Don't forget the hashtags now on YT #resist #resisters #resistors =)

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.
Amazing Chanel to learn electronics thanks. Thanks
Great video Karen! Thanks!
Love your videos Karen, awesome job and so informative!!!
Can you please make a video about smd inductors and how to read the value? I want to replace some inductor on my laptop board..I can't find anything on internet...R68322RQH this is the inductor
Where can I find posters like the one in the background and others with helpful reminders that I can put up in a shop?

I really like this video! You have corrected some my bad terms for a couple of parts. I should sound smarter now. :-)
You forgot to mention potentiometers come in linear and tapered, and you can parallel up low wattage resistors for higher current handling
Karen, i love you stiker of the ben heck show on your laptop. keep on the good work. thumb up.
Dear lady your knowledge is impeccable but for us trying to learn Please slow down a bit
Well explained! need to sort my Box-O-Resistance....some day...not today
Would that be a Borg Cube? (But that would make the resistance futile, I guess.)
It's hard to resist an great explanation by a talented lady :)
What kind of variable resistor control with code using gpio pins?
8:22 isn't the one on the right a variable inductor?
Really
Great video,
I like your learning.
wow you explain so well !
Thanks, Karen!
How to count velue of two resistance in parallel connection.please describe it. From Dillip Kumar India
Very useful video. Have you moved shops now Ben has left, I assume that Ben owned the original shop in your recent videos.
Still in the same shop, I have just turned the "break room" into my office/workspace. Because window and because sound isolation.
Where Can i learn to repair electronics?
Aww.. thanks Karen. I always thought rheostat was just an obsolete word for potentiometer.
We used to just call them pots
I love it when you talk science to me...
No really, I’m much smarter after watching this! :)
Lovely video

Coudnt resist the vedio.....thanks Karen....
*matching resistors is like matching eyes with sweater*
Nice video
Thank you teacher
Looking forward to a transistor video or two. I assume capacitors and coils will come before that.
Lovly youuuuuuu I like your approach
Karen should have been the new host!

Spectacular
I’d have to say capacitors are more fun to watch explode than a resistor is burning up 🤓😜
Thanks👍
I cannot resist her. I'm over heating!
rob peters you jerk of while watching?
Superconductors don't have resistance, but as of now, it's unlikely you'll just come across one. :)
I wish they didn't change the color of resistor bodies to Blue it makes them so hard to read
Thank karen v useful
Thanks for the info, the comments are creepy...
karen is neat
Karen are you from united state??
Or Europe!!!
I grew up in Michigan in the United States and now live in a different state, Wisconsin.
"South Canada" 😉
So the dimmer is a giant resistant ....
that it is - as is a volume control
The cutest ever...
Where the heck is Ben Heck?
Brian H welcome to the channel, are you new here?
Resistor!? I barely touched her! And don't call me Shirley.
😍 Isn't she wonderful💝
Hey! You're not Ben Heck!
Nope. I'm Karen. Hello!
I'll vouch.
🤔
Got here from janku
Informative video ... and great rack
I can't resistor O:-)
i love you .
Because you dont speak in spanish. 500.000.000, people speaker
MILKY MILKY WARM AND TASTY
Nice bewbi
nice i love you will you marry me pls
