A beginners guide to relays, contactors, and solenoids to automate anything; (#083)

Thank you so much for watching. These kinds of videos are my favorite! I am so happy to be working with Kiwi Co on this. It would be a big help if you supported the channel by visiting their website, and trying a crate or two! Your family will love it, and it is 20% off www.kiwico.com/JeremyFielding

I'm an electrical engineer and I know this stuff ... but I watch cause I love the way you explain it ... you are a very good teacher!

The older I get, the more I think, "Damn, to think think I'm getting this for free while I'm aware of the price that people paid for this knowledge." Thank you Jeremy for sharing more valuable info with us while demonstrating to us your wonderful family. The combination uplifts my spirits.

If all families had parents that engage, inspire and interact with their children like you and your lovely wife, the world would have no problems. Great video - great family - great teacher: thank you, sir!

Probably the most in-depth, single sitting, instruction I’ve ever received for relays. This may as well have been a 1-2 hour class anywhere else.

"if you want somebody to be interested in something, you have to inspire curiosity" amen to that sir! Great video Jeremy, thanks for sharing.

Your wife's reaction to being filmed was heartwarming! You're the best Jeremy.

regarding "is it a short?": when you first apply a voltage to the coil, its inductance impedes the flow of current. As time goes on, that affect reduces until only the resistance of the coil is relevant. If the coil is long enough, and the wires thin enough, that resistance can be high enough to safely connect across your voltage source. If the coil is too short or has wires that are too thick, that resistance can be low enough that it will try to pull too much current from the voltage source. If your coil is short enough or has thick enough wires, you can reasonably argue that the result is a short circuit. This is why solenoid controllers exist. The controller may need to reduce the voltage given to the coil after it is initially switched to prevent excessive current draw.

Loved this video. "SO" well explained! THANK YOU for the effort and time you put into this wonderful content brother!

I came for the knowledge but left with relationship goals... on top of knowledge. You seem to have a wonderful family! Oh, man I get to touch the thing that say "don't touch"?! #disbelievinggrin That cracked me up!

Jeremy, you're a treasure. Like Destin Sandlin, Mark Rober and others, you create content that both informs and entertains like few others are able. Thanks for sharing your family in this video. You're definitely a very fortunate man, husband and father. In addition to contactors and relays (including solid state), a good follow-on to this video might feature MOSFETs and transistors. In addition to activating and switching currents, viewers should consider cycle life and parasitic draw of all these switches; especially in battery systems (which make up much of my applications).

I'm getting to the point in my electrical career where the concepts are intertwining and I can better describe how an electrical system works. You've helped do that for me. Thank you.

This channel restores my faith back in humanity.

Beautiful wife and family! You're definitely blessed my friend.

What a great and straight forward teacher! much love from an electrical apprentice/ tinkerer

I love hearing people explain how things work . Especially folks like this who actually know what they are talking about. Thank you. You doing a good thing.

This guy is a great teacher, and more importantly shows us that he is a good husband and father. Keep inspiring young minds man. Thanks for donating your time to teaching others all while being a great example.👍

Dude, you have got to be by far one of my favorite channels to watch on YouTube . You know ur stuff so well and I can tell you love learning and teaching, you are an amazing teacher because it’s obvious that to truly love ur craft and love to share it with others, i too love this craft or what I call an “Art form” because of the limitless amount of creativity possible. I learn and do more and more every day with the help of your channel. You are immensely talented and inspirational. I love that you are continuously learning new things all the time yourself and never treat your audience like they’re stupid for not understanding something right off the bat, instead you take your time and make sure to break it down explain things in great detail with visual representation throughout the entire educational process. You are undoubtedly bettering yourself and the world, and not to mention your incredibly humble and passionate and patient, not to mention just seem to be genuinely a good person who is real AF. You explain everything so well and I find you beyond inspiring. Thank you for all the time and hard work your put into your videos and craft. I / we/ the world… is so lucky to live in a time where content like your channel is available 24-7 all day every day for FREE! If that an’t some amazingly dope shit I don’t know what is. Anyways man, keep it up dogg your a true G. I’ll stay watching, stay inspired, and stay learning from you as long as you do! Thanks again - SHMIKEDOGG

I love your down to Earth and simple explanations. Even your sponsor was perfect for the environment your inspire with your family. Thank you.

Jeremy does a good job of breaking down the mechanics of things so that anyone can understand. And he seems like a great guy. So much enthusiasm for what he does. He would be the best neighbor to have. I could hang with him in his shop all day long.
