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.
Itâs easy to guess where the hottest place in the universe might beâthe core of a giant star, maybe, or a disk of gas heated to millions of degrees as it tries to cram its way into a super-massive black hole, or even, for a fraction of a second, a fusion reactor in New Jersey.
