THE LED require series resistance but in our home there is bulb ex. 60w,80w etc
does not require R series ,why?
why the R get increase on heating what is the use of gas?The bulb is just a resistance wire coiled up, as the bulb heats up its resistance increases, limiting its own current.
The gas (if used) excludes oxygen so that the wire doesn't burn.The resistivity of the tungsten wire used for the bulb filament increases with temperature. It is a fundamental physical property of tungsten.
The gas (if used) excludes oxygen so that the wire doesn't burn.
what this mean burn?The gas in incandescent lamps is usually Argon, or Halogen, as it does not burn.
I'm on the fence about that; right now, my money's on "(word removed by moderator)."I am now convinced Ritesh is a troll.
No, we're not forced to read it but he's a troll nonetheless. Nobody's forcing us to read spam here either, but that's deleted on sight....Let's keep it polite. Nobody is forcing us to read any particular thread or post.
I didn't say he wasn't entertaining. And, as far as trolls go, he is one of the best around. Look at the volume of responses he is able to generate!Let's keep it polite. Nobody is forcing us to read any particular thread or post.
It's how he spells axle, but the rest of the US spells it a-x-l-eJoeyd999
Is that how you spell axle in the US?
Embarrassingly enough, no. But I'm not putting much effort into this particular thread. I'll pay better attention in the future. Thank you for your concern.Joeyd999
