Experiment "electric arc and the composition of the electrodes in air"
Together with the experimenter Slobodan Stankovics we will look at the spectrum obtained from an electric arc in air.
Points of interest:
- several different electrodes - different chemical composition Fe, Cu, W (more?) alloys
- Spectrum before and during the electric arcing of the arc/air while operating.
- chemical composition of the electrodes before and after arcing.
