Discussion Overview

The discussion revolves around the inquiry of whether there exists a chemical that emits light when a 12-volt charge is applied. The context is homework-related, focusing on the properties and brightness of such a chemical when energized by a 12-volt source.

Discussion Character

  • Homework-related, Exploratory

Main Points Raised

  • One participant asks if there is a chemical that glows when a 12-volt charge is applied.
  • Another participant suggests tungsten as a potential candidate.
  • A follow-up question is posed regarding the brightness of tungsten when used with a 12-volt battery.
  • One participant confirms that car brake lights, which use 12V tungsten bulbs, are indeed bright.
  • Another participant reminds the group that this is a homework forum and that there are rules to be followed.

Areas of Agreement / Disagreement

There is no clear consensus on the initial inquiry about a glowing chemical, but there is agreement on the brightness of tungsten in the context of car brake lights. The discussion remains somewhat unresolved regarding the specific chemical properties and alternatives.

Contextual Notes

Limitations include the lack of detailed definitions of "chemical" and "glow," as well as the absence of a thorough exploration of other potential candidates or conditions under which they might glow.

Tungsten :eek:

hi, thanks for the reply, this chemical would glow with a 12 volt battery,and do you know if it would be bright, thanks again
 
Yes to all your questions.
Car brake lights are 12V Tungsten bulbs. That's plenty bright :smile:
 
Umm...this is the homework forum. There are rules to be followed.
