Love the video! I was wondering if you’d ever make a video about forms of testing? E.g balance testing for motors or something like IRs? But general one would be really appreciated thank you.
Thank you very much for your simple, clear and accurate explaination. You cleared the cloud which in my head for years about relay. Now my mind has been satisfied and relaxed. BIG THANKS!!!
HUMAN's lifetime is not huge or enough for earning knowledge to make themselves as a ruler of the galaxy but if you work hard maybe you can able to rule yourself. wishing you good luck.
I didn't understand how SSRs worked before now. I've been looking everywhere for an explanation on how they worked and this video is the first to fully explain it and give a picture as to how it is working. Thanks!
Im well acquainted with mechanical relays, from small 24VDC ones all the way up to big 460VAC 8 pole relays, but I stayed till the end for the flywheel diode explanation because the nerds on stack exchange were either extremely rude and belittling (as per usual with that toxic website) or they over-explained with lengthy lectures with a bunch of laws, theory, and formulas. You managed to answer that question in under 30 seconds. You are a legend
I know a ton electrical apprentices would love a video on conduit bending. Formulas for finding the right bend degrees and how to bend them. Your guys visuals are the best!
Great video. Very clear and helpful. In the AV industry we typically see relays in control systems, such as to raise or lower a motorized projection screen.
its 3am here i have nothing to do with electronics but you videos are so satisfying i give huge amount of knowledge love your channel keep up the good work!
I really like combination of timed relays and 3-phase relays to make automatic star-delta switch for 3-phase motors. We used to connect them together in technical school at practical lessons. That was fun. However few guys who were not careful enough got shot from 230V AC. 😏
Learned a bit more about latching & double pole relays. Had this idea of using relays in an inverter project, so can switch between inputting between 12 or 24 volts DC. Simplistic pictures and animations work very well in explaining things.
Video: 3:10 - We've looked at solenoids in the past, and check out that video, link in the description below. Me: CTRL+F - "sole" - No match found. ???
The term back means it opposed the change. In this situation, the change in current is opposite of the direction of the current. So the emf produces current in the same direction. Emf always acts to keep current equal, so it opposed the direction of change.
Great video. We studied relays during my college course and this video helped as a refresher. As for where I've seen relays used, I've seen them used in elevator controllers, fire alarm panels (latching the signal), HVAC equipment and traffic signal controllers to name a few.
Hey! thank you for this great video. I'm looking into installing a PID controller on my espresso machine (my background is not in engineering) so this really helps me to understand the parts needed to make the controller to work. Thanks!!
Hi there! I have seen relays at my workplace. We typically use them in automation. We have heater banks in AHU and we remotely operate them via SCADA/CMS. So the command signal is sent to the relay which then provides the power supply to the heater bank.
Making a fused, relay box to control a switch panel for a bunch of lights on my side by side… the shop was gonna charge me 2500 lol I bought all material and lights for 300 hahaha thank you for teaching me how useful relays are. We pay for the information we don’t know, I’m thinking of starting a business on lighting circuits…. Thank you 🙏 Blessings on you and your family.
Very clear explanation, thank you so much. I just rewired a fog lamp with a 4-pin relay today on my motorcycle. Should I add a Flywheel Diode? (Just broke a fuse yesterday lol) Thank you, greetings from Indonesia. (liked and subscribed sir)
7:21 - I used a relay to make a multi-flow ebb & flow hydroponic controller bucket. Wasn't my design -- I followed a DIY I found online, bought the parts, and put it together; *but it worked,* and it was extremely gratifying. It involved float switches, a timer, and water pumps
DUUUDEE!!! You are very grand!! All of your videos! Your videos will butterfly effect huge innovation in the world I'm sure! People like you are making the world a better place.
Thank you so very much for these very perfect and outstanding explanations, please just as a matter of more favors, define some about current relays too.✌🙏
Thanks for clarifying the details about the functioning of relays... I want to manually design a remote controlled light with a relay... Could you please help with any suggestions?
I've been doing some project electronics recently and am definitely at beginner level, I had no idea about back EMF, exceptionally well timed and a great video as always. Thank you!
Thank for this wonderful video. I'm not fully sure if it a correct statement to categorize "Optocouplers" as "Relays". Even thought they are used on some Solid-State Relays. What I have learned from my EE course and books that Optocouplers are Optocouplers and Relays are Relays. Thanks.
How do you calculate the power consumption of a relay? E.g., SONG CHUAN 833H datasheet says: Coil Rating (DC) Rated voltage 6V, Rated current 60mA, Coil resistance 100ohm. How come the Power consumption at rated voltage is approx. 0.36W?
In the last circuit, the diode only works due to current flowing through the path of least resistance or the shortest route. That wouldn't help the LED all the time, so shouldn't the diode be placed in line with the + lead between the LED and coil?
Standard tattoo machines have an alternating relay which serves as a drive force. Same as old school bells, the armature bar connected with the spring drives the action.
I love your work and explanation and I am going to become a monthly supporter (I am not an engineer, not do I work in your industry , but I loved this type of stuff.) Can you perhaps make a recommendation about which books to buy for electrical basics and a bit more advance? You can monetize Amazon links from the books you recommend. Cheers and keep up the good work .

Best explanation on relays ever I heard, Thanks
I want a teacher like you.
You are most welcome. We are your youtube teacher
@@EngineeringMindset yes I have some ideas want to share with you and thanks for your best video.
Me too
Agreed I learned more off this short video than I did going through my apprenticeship lol
Same though! Amazing
I'm now smarter after watching this. Soon, my knowledge of all things will be complete and I shall rule the galaxy!!!
Lol then the creator of the video is already ruling the galaxy😂
🤦🏿♂️✊
Is this a reference to something?
HUMAN's lifetime is not huge or enough for earning knowledge to make themselves as a ruler of the galaxy but if you work hard maybe you can able to rule yourself. wishing you good luck.
Rock on brother
Thanks for relaying all of this great information :)
smooth, I like what you did there
HA!
I am an electrician mate with US Navy,you are a great resource!Thank you

These videos are really amazing. I am in hvac school and these videos are unlocking lots of understanding. Thank you for taking the time to make them.
Thank you so much for these extremely thorough crash courses! These are just amazing.
Im an industrial electrical apprentice and this video helped me understand relay circuits a ton !
For next topic, could you enlighten us about explaining piezoelectricity ?
I know a ton electrical apprentices would love a video on conduit bending. Formulas for finding the right bend degrees and how to bend them. Your guys visuals are the best!

Thats one wonderful video that explained very clearly about relays. Thanks so much
I have seen relay in electrobooms video
When he makes a taser 🙂
This is how internet and youtube should be used. Thanks
This was fascinating Ty!! Someone tried to explain this using paper and a pencil. I said no thanks I’ll watch a video!
i also thought back emf pushes the electrons or current in the opposite direction, hence "back" emf....
The term back means it opposed the change. In this situation, the change in current is opposite of the direction of the current. So the emf produces current in the same direction. Emf always acts to keep current equal, so it opposed the direction of change.

This was so incredibly helpful. I'm in school for automotive tech and the first class is electrical..Thank you so much.
Sensible pace, great graphics, well narrated. Excellent…thank you.
Thank you sharing your advance information of electronic engineering, I have learn your knowledge and most of its easy to understand
I'm an auto technician, so relays are a daily thing.
I think u r saying relays.. #typo
Spelling too right?
@@PrabhjotBhatti I am now. :)
Tell more, how you use it in auto.👍
thank you Paul, for making me smarter in the sense of electrical engineering.
The stuff people come up with man... Very clever
Hey! thank you for this great video. I'm looking into installing a PID controller on my espresso machine (my background is not in engineering) so this really helps me to understand the parts needed to make the controller to work. Thanks!!
What a great video this is! You guys make millions of lives easier! Keep the good work!

I've had a few close calls in the past, and I've learned the importance of wearing Softgle.
Well, that's it...now I know everything. Thanks for a great video.
Thank you for your awesome video. I have a way better understanding now
Your videos are very easy and straightforward that it explains all the details practically
OMG, after watching this footage i totally understand how relay works！
Love your content on electrical engineering
Another great video!!
Please do one on contactors.
I'm an elevator mechanic, I don't have the cognitive capacity to figure out how many relays I have replaced in the last 12 years
So relays go bad quite often? Are they the first thing you check when something electrical is wrong?
Hi there! I have seen relays at my workplace. We typically use them in automation. We have heater banks in AHU and we remotely operate them via SCADA/CMS. So the command signal is sent to the relay which then provides the power supply to the heater bank.
How can we desid wire size and no of turn of empty core of a motor
Absolutely phenomenal video.

Absolutely brilliant
Brilliant explanation 🙏
Heyyy...You done a great job man....
Relay logic is fun. :)
the best explanation, it clears my all doubt about realy.
Well explained, thank you
*FANTABULOUS WORK* 🤗
Thanks for clarifying the details about the functioning of relays...
I want to manually design a remote controlled light with a relay... Could you please help with any suggestions?
Helped me out alot, still abit lost on some bits but thanks for the explanation 🙌

2nd time I've seen this dude today
Very informative ✊🏿✊🏿✊🏿 ... radios 📻 and cellphones would be cool as well
Better than my college classes
How do you calculate the power consumption of a relay? E.g., SONG CHUAN
833H datasheet says: Coil Rating (DC) Rated
voltage 6V, Rated current 60mA, Coil resistance 100ohm. How come the Power consumption
at rated voltage is approx. 0.36W?
Good job
Well done 👌👌👍
In the last circuit, the diode only works due to current flowing through the path of least resistance or the shortest route.
That wouldn't help the LED all the time, so shouldn't the diode be placed in line with the + lead between the LED and coil?
Do a video on the concept/theory of the Tesla Coil
Standard tattoo machines have an alternating relay which serves as a drive force. Same as old school bells, the armature bar connected with the spring drives the action.
Really good video
