It's literally the fingerprints of god being left behind. That's how I see these math equations in everything. Many people try to separate religion and science-- but I tend to see it as evidence. lol
Hi Craig, I thought the starter was normally open then closes when the neon heats up within it. Then when the Ne cools the switch opens and causes the spike voltage. Are you saying its normally closed?
its a simplified explanation. yes they start open, quickly close due to current flow causing electrodes to bed into each other, voltage shorts out to supply then cool and open again and allow now excited tube to receive full ballast voltage and strike..
Yeah I played it to my students and they looked baffled..... Epic fail 😔. I thought I'd broke it down enough. I really like putting it all together because the text books rarely do that but I'm not sure anyone else cares 😂
@@cestemshow I watched it back again earlier, and the penny dropped I think!!🤣 that’s the beauty of watching on a video, you can rewind it until you get it, all your videos are really appreciated, thanks 🙏
So is a ballast literally just a coil, or is it a transformer that steps up the voltage? Is there a way to test the voltages of a ballast? Or do I have to pull it all apart and ohm it for a short like everyone else shows in their videos. I came here just looking for the output voltage of a ballast. lol ... brought me back to my electronic days in vo-tech in 2000.. so I subbed
Thenks to the "Made in CHINA" phylosofy. ... - we don't need to know anything - just go and by entire new unit and screw it onto the wall. Lol... I am just fixing bunch of thise thrown out. Freebies. Lol... Nice math lesson... Makes me thinking of Pitagoras from SAMOS. He created first comunist utopian colony... but that is for another video.
This video literally, saved me, did not get it untill this. Keep it up man subscribed
40 years in the field and needed a refresher to fix a light, your video was spot just what i needed.
35 years in this game , still enjoy all the math side of things, trig etc , great video
Yeah me too. Its actually relaxing nowadays to simply work out some triangles. 🤷♂️😂

I missed a day a college due to illness, I'm caught up now. Thank you Craig, much appreciated 👍
Thanks from Bangladesh.
You did fantastic 🙏 please do a video on led bulb where real power and the current is only stated. ( I mean no power factor 🙏)
Anothet stunning video. Awesome content Craig 🙌👏👏👏
Thanks Mark. People are saying they can't follow it, what did you think?
Preparing for my exams , thanks alot, for your help
Good luck!
@@cestemshow thank you sir

How many fluorescent lights actually have a capacitor ? Where is it located in the light
Most older ones. Modern ones have a hf unit all enclosed.
If they have one they connect it across the supply terminals.
thanks for this video, it is very helpfull for me to understand it
Thank you for the knowledge ☺️
My pleasure 😊
Another great video mate good to see you got your hair back 😂👍
Thanks Ash, it's shaved again now...... You can see the bald patch well on this vid 😂. You good mate?
Yeah mate all good how you doing
Just perfection
Hello, If I have to tap and or wiggle the bulbs for them to turn on, what's the problem ?
Would this work with an led light?
Nice one Craig, you made that look easy👍 I think I’ll have to give it another watch tomorrow🤣👊

You are funny...I don't know if it was your intention 😅.

Its just a coil. Never tried to measure the output voltages when striking? I will have a think and get back to you
AC RLC theory
@18:38 btw you could have just multiplied by C capacitor value and divided by the 450 resistor value.
Edit: seems like you did it on purpose so nvm
Finally you used 7 nano instead of 7 micro. Why? I don't understand brother

Do you have a bank account in a community bank ?
It's a little silly to use A for amps and I for current on the same board.
Pick one and stick to it. lol
Difference between the symbol for current and the units measurements of current. Catches out most of my students at the start :-)
Thank god we have LEDs.
