Hello there:

I need to calculate the expansion (area) of the tungsten when current and voltage is applied in it as conductor.

The expansion will depend on the thermal coefficient of expansion, and the temperature rise.

The temperature rise will depend on the power dissipated, and the thermal impedance between the conductor and the surrounding environment. You may need to characterize your physical setup to determine its thermal impedance (in degrees C per watt).
