Условие

A thin brass wire can be used as a fuse. Find the correlation between the critical current and the wire diameter. [23]

Note [23]

“A thin copper filament”, according to the 2006 English version; “dart”, according to the Belarusian text. The Russian and Belarusian texts are the most straightforward, just saying “Investigate the dependence of the current at which the dart burns out on the dart diameter”. [Kopelevich 1992] reads here, “Find the correlation between the current of the wire and its diameter”, not saying directly that the wire burns out
