Robert Cinca - Physics How I measured the cross-sectional area of the filament I measured the cross-sectional area by zooming in into a single turn in the filament and measuring it using one of the measuring tools available in the software (see Figure 12). Figure 12: Measuring the cross-sectional area How I measured the thickness of the filament To measure the thickness of the wire, I used a similar process as I did for measuring the cross-sectional area (see Figure 13).
