Вопрос № 1015618 - Английский язык

According to their resistivity, conductors are divided into two groups; the first includes materials with low resistivity: copper, aluminium and others. These metals are used to produce wire conductors due to their high mechanical strength. The second group includes materials with high resistivity: one of these is nichrome. Due to its good heat resistance, nichrome is used to produce heaters. Carbon is commonly used to produce electrodes and brushes for electric machines.
