What is the conductivity of sugar?

Sugar, in its solid form or when dissolved in pure water, does not conduct electricity. This is because sugar molecules are covalent compounds and do not break into ions in solution—ions are essential for electrical conductivity. Unlike salts, which dissociate into charged particles, sugar molecules remain neutral when dissolved. Therefore, a sugar solution lacks the free-moving charged particles needed to carry an electric current. In short, sugar itself is a non-electrolyte, making its electrical conductivity practically zero under normal conditions.
