   Can we get a video on Graphs indicating Overdamping, underdaming

   The spots welders at my workplace is not functioning. Fisrtly thought it is relay since it didnt get energized. But then, its actually the transformer didnt supply enough. Nevertheless, this video give me a deeper insights about relay and I love it. Thank you.

   Great video. I use relays all the time in my vehicles. Currently using a 5 pin changeover relay to disable my daytime running light LED when the parking brake is pulled. This way I can idle dark at night if I want. Ignition power to coil, Parking brake grounds the coil, ignition power to 87A out to 30, pull the parking brake which triggers the relay action and subsequently cuts power to the DRL as it connects 87 to 30. And since the coil was tied to the parking brake ground, the coil was bacjfeeding my instrument panel LEDs a bit, so I put in a diode so nothing can travel up that wire back to the panel/cluster. No more funky behavior after that since the coil electrons can only flow straight to the parking brake ground now. Love using electrical parts in unique ways to accomplish a goal.

   Definitely learned more about them from this video too. I understood electromechanical relays fine but never have used a SSR. May have to try one one of these days. I typically use Bosch changeover relays for everything I do as they are most common, and sometimes I’ll user one with a timer. Hella makes some good ones.

   The animations plus the way you concisely and effectively explain the concepts is just purely awesome. Thank you!

   I am a high school student of 9th grade I have never seen a relay, I listened its name in a computer science basics course, and I didn't understand it , and I saw it for first time in your video.

    The quality of this and other videos is unbelievable! I finally know what all those terms mean 😀 (what do you use for your graphic generation?)

    Hello Sir, I am planning to modify my electric trolling motor newport vessel 62lb 12v 60A to remotely operate. I bought Remote RF switch circuit 12v 20A to adjust the speed for trolling motor. The current rating is quite different motor and the switch circuit. Do I require to use the relay for that? And also I'm not sure where to put the relay. Could you please tell me any suggestions? Thanks 🙏

    which side of the relay would the diode be placed?

    The feed in to the coil side or the other side controlling the NO/NC switch?

    Or both?

    Also, how do you calculate what size diode you would require?

13. 

    what type of relay would I use if I wanted to take a 230v UK mains supply to simply close a circuit?

    I want to fit an always on extractor, however, it reports it has a manual override that can be operated via an unpowered switch. I figure that the fan has 2 contacts, one of which is powered and the switch simply closes that circuit.

    Problem is, I will have a switch which will be providing 230V. Also, the switch is a smart switch that I can control via my smart home.

    If I can get this to work, it will allow me to control it via other sensors elsewhere on the house.

    Thanks for any feedback

    Great explanation nice video

    Does a relay for a led light for a car require a minimum 12v dc battery can u put it on anything bigger or smaller of a battery, going to Put it on my mower

    annnd that's officially too much youtube for one night…

    This video should have 10x the views it has.

    I am currently using a normally closed relay in combination with a tone decoder circuit in order to operate a safe that opens when the right frequency of sound is playing.

    My oldest knowledge got some coolest brush up. Now I know why the younger generation is smarter.

    So nice

    Good morning

23. 

    I seen using this Relays on high power transformers…!

24. 

    Well explained and animated relays functions,, looking toward getting more knowledgeable, thank you

25. 

    Thanks it make good points

26. 

    Thanks

    Really enjoyed

    if there is a battery on pimery side, why there is a battery on the secendry side ?
