Why does the temperature rise when the graphite powder is turned on?
The presence of resistance, melting point at 3850 + 50 degrees C, graphite powder is a very sensitive chemical substances, in different circumstances, his resistivity will change, that is, his resistance value will change
What is the value of resistance, and this value is not an accurate number, because the graphite powder thickness is not the same, used in different materials and environment, graphite powder, resistance value will be different.
But one thing will not change. Graphite powder is one of the best nonmetallic conductive materials. As long as the graphite powder is kept inside the insulating object, it will electrify as a thin line
