A student measures the current through a newly developed conducting polymer filament at various potential differences. Table 1 shows their results.

Table 1

Potential difference (V)	Current (mA)
0.5	1.2
1.0	2.4
1.5	3.3
2.0	3.8
2.5	4.0
3.0	4.0

The student uses these results to write the following conclusion:

"Since doubling the potential difference from 0.5 V to 1.0 V doubles the current, the current is directly proportional to the potential difference across the entire range, and it continues to increase throughout."
