James Watt had a limited formal education, having attended a local school in Greenock, Scotland, where he showed an early interest in mechanics and mathematics. His education was primarily self-directed; he apprenticed as a mathematical instrument maker, which provided him with practical skills and knowledge in engineering. This hands-on experience, combined with his curiosity and ingenuity, played a crucial role in his later inventions and contributions to the steam engine.

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.

The prongs of an electrical cord are made of metal to efficiently conduct electricity, as metals like copper have high conductivity. In contrast, the cord is coated in rubber to provide insulation, preventing accidental electrical shocks and protecting the wires from damage. The rubber coating also enhances flexibility and durability, making the cord safer and more user-friendly.
