  • The title tells about the voltage, not the current.

    Graphite has a Resistivity of about 8 Ohm*mm^2/m.

    Letzt say their part is 5cm long and has 3 mm^2 (A short piece of a pencil). Makes 0,133 Ohm. What will result in 180 Ampere with 24V.

    The power supply surely has a limitation for the current. I think max. 20A. What still is 480 Watts heating power.

  • wouldn't be surprised if you guys die young.
