The electric current passing through … WebMar 14, 2016 · The resistivity of copper is about 1.68*10^-8 ohm-meter. We can now look at the current required to heat it to 70 degrees. This will depend on how much energy will be lost from the rod to its surroundings. This is not easy to calculate, but we can make some assumptions. If we assume that most of the energy lost is due to convection and not ...
WebMar 25, 2024 · A typical heating element is usually a coil, ribbon (straight or corrugated), or 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.
