A typical heating element is usually a coil, ribbon (straight or corrugated), of strip of wire that gives off heat much like a lamp filament. When an electric current flows through it, it glows red hot and converts the electrical energy passing through it into heat, which it radiates out in all directions.
The sun has a surface temperature of 5,500 K, typical for a yellow star. Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star.The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.Stars are fuelled by the nuclear fusion reactions at their core.nce the nebula fades, the core is called a white dwarf, and has a temperature of 100,000 K. This cools slowly, over billions of years, to become a black dwarf too faint to detect. This is the end of the starâs life.
