Why aren’t electrical prongs hot when they’re removed from an outlet?
Heating occurs when there's a significant amount of resistance. Significant resistance can occur if the material you're using is a poor conductor, or if you're using a conductor that's physically too small. In the case of the prongs of a plug, they're both made of metal (good conductor) and fairl…
The Short Answer
Heating occurs when there's a significant amount of resistance. Significant resistance can occur if the material you're using is a poor conductor, or if you're using a conductor that's physically too small. In the case of the prongs of a plug, they're both made of metal (good conductor) and fairly large in size. Therefore, there's no major resistance, and they don't heat up noticably.
