@@ZeldagigafanMatthew Doesn't mean he hasn't deadened his nerves. I'm a professional too... I once stood next to a panel holding a 18 gauge signal wire that was shocking me, all the while pondering how it had enough current to go through my PPE. I wasn't touching anything but the wire by the insulation, the current wouldn't have been able to flow any way but through me, my electrical boots, the rubber insulated mat, cement floor and finally to the ground. Still have no clue how the current for that particular signal wire was so high.

Any large body acts as its own earth, as the AC signal is constantly charging and discharging the capacitance the body represents. The are a number of ways an active load could superimpose an AC signal, even on its DC supply, but such a condition would-be the result of bad design or very high power.

I designed things with relays for decades. Far too much of what was in this video I had to learn the hard (smokey) way. Adding the zener diode was new to me though and is a brilliant simple solution when faster response is needed. Back in the day I used more costly solid state relays when I needed faster response. Could have saved buckets of $$$ using $0.10 zeners instead.

Several people had theirs hooked up so that the bulb was on when the switch was open, and off when the switch was closed. They ran their batteries down pretty quickly.

One random thing I'll add is that they have a lower contact voltage rating for DC than AC,because there are no interruptions to the current that would let the arcing stop. A relay designed to switch 5A 120VAC might only be rated 30VDC, and might arc permanently and burn up when "switching" 80VDC 3A.

@justan idiot I believe the 2000v thing he's talking about was a while ago when he built a "Jacob's Ladder" using a microwave transformer. The device appeared to fall onto him while powered on and shocked him badly. I know he fakes shocks and other accidents to show potential mistakes you can make, but if that really happened the way it looked he's lucky to be alive. Those transformers can put out .5 A or more, they have enough voltage to force that through a human body, they can easily kill or burn tissue from the inside and they've claimed a number of lives.

It's always nice to search for relay videos, only to realise that your favourite electronics youtuber has already done a video on it. Thanks Mehdi

I really love your videos, it’s both funny and educational. Your videos literally helped me pass my truck electrical class. Which is important to me because I’m planning to become a Diesel Mechanic. I’m almost done with the program. I finish the program somewhere in September.

I use a relay like the first black one you showed to make a ignition circuit for a ~1930’s 3hp engine on a railway inspection cart made to carry about 2 people. It was missing its ignition system except for the points, and a single spark wouldn’t ignite it, so it was set up like how it was set up in the video to buzz, except it operated a 6v car ignition coil to make high voltage.

4:23 Damn! Took Me a while to wrap my head around that. Only when I looked at the relay terminals a few frames earlier, did I understand. This was so cool!

I've discovered that relays give shock when powered off in the past by own experience. Same apply to solenoid valves and other similar stuff. Also, quite a crap of unreliable technology but still very widely used due to it's unique properties.

Relays are pretty reliable if used correctly.

Never had one from a relay. Capacitors... They can bite days after use, as i found out when i grabbed a used one from my compressor run/start capacitor spares parts box

I don't buy it. They can't stay charged like a capacitor can.

At 10:00 you mention release voltage. Can you do a video about peak-hold driver circuits, like ones used for fuel injectors?

For real though, I really freaking like how he can be really fucking smart, and a chaotic dumbass in a flip of a switch, mix that with him forgetting some stuff that when he remembers looks obvious, an you have a amazing channel with crazy good videos
