Relays - How they Work

[nixonpunk222]

Thanks for the great info! Im wiring to fans into my truck to get rid of the stock clutch fan now. Before I knew about relays I was just running fuses and keep blowing them up hopefully this will fix that

[dalsenov]

Thanks!!! Veri informative!

[gnbnoto]

awesome video man , i actually learned sth

[tayyabchau786]

my right ear is lonely :(

[hotpapayasalad]

THANK YOU!!!

[JD8853]

hey , can relays work so they can turn something on when the power to the coil is turned off?

[ljcalma14]

@JD8853 the presence of current in the coil creates an electromagnet that closes the switch. no current = no magnet = no switch

[JD8853]

@ljcalma14 ive already reversed it. when wall power goes off. the battery circut is complete

[jeffcoolstuff]

great explanation!!

[Lagonz2000]

Ha ha ha, such a simple explanation, GENIUS!

[itspennysboat]

thank you so much sir. helped me a lot!!!

[TOW4LESS1]

hey wt about realy when it says 87 nomal open and 87 normal close and 87 a, can u come up with this solution thanks.

[DeOppressoLiber23b]

How do they blow or how do people blow them?

[ihsanullahable]

thanks sir nice presentation

funny how males refer to objects as females

wounded if there is a connection there

[Hummve77]

You should narrate tv shows. You have the voice and clarity. I thought I was watching a documentary on the history channel. Good work.

[matthewtchernev123]

can you use the same power source for the coil if not will the power source short with the coil

[Annergize]

What is the point of a relay though? It's just a switch that requires current to work, unlike a regular switch. How does it benefit the circuit?

[360xi]

@Annergize True but the difference is that it can control higher currents better. Imagine turning on headlights with tons of AMPS going through the steering wheel, it would get HOT FAST. However with a relay and good location you can control higher amps more safely. I get your point though.

[Annergize]

@360xi Oh so is that there only purpose?

[360xi]

@Annergize I believe so. Still there are some relays that confuse me cause they have 5 or even more teeth.

[MrKornKid]

Question though, if a relay is getting 12v from the battery, what is there to convert? I get that the answer is amperage. But what I dont get is draw. So instead of say a fan drawing 12v, 15a, the relay draws 12v, .1a and converts that to the 15 required?

Also, what stops the relay from producing too much current?

[Mustured10000]

does anyone know if i can use a relay for my voltmeter... it stays on all the time so i figured i can use one. but i need it to let quit a bit of voltage trough around 15 volts so if i use one that says 12 volts will it work or do i get one that says 24 volts or does it not matter? =/

[mansonia67]

...thanks brader ..god bless you

[manoj6418]

really good...

[stormloader909]

very good !!



[subzerostorm]

Mate that was... brillant :) So simple

[TheRabidMoths]

I wish my teacher explained relays this easily.

[ZMclovinFan64]

Thank you so much for this video. I've used relays before but never actually understood how they worked, but thanks to your video it seems so easy

[ocmc32]

Thank God you just saved my Physics GSCE. I couldn't understand this for the life of me, but you make it so blody simple. Thank you very much mate.

[ocmc32]

@ocmc32 *bloody

[vijayraskar2003]

great

[MYBLUES74]

if only everything was a easy to understand as this. nice one mate

[randy97590]

thnx for information

[ironman2712]

great video-now I understand what is all about-thanks

[stormbytes]

Wow Excellent Presentation! Seriously.... You REALLY explained it well!

[HARTB18C1EG6]

so simple to understand. great job

[bozcopcspecilaist]

Very simple and straight forward.
