The mass of one mole of any substance, expressed in grams, is by definition its molar mass. One mole contains the Avogadro number of particles, about 6.022 × 10 23, so the molar mass links the mass we can weigh to the number of atoms or molecules present.

A fuse must carry the normal current, so it must conduct, and it must melt quickly when the current becomes too large.
