One of the mysteries of the English language finally explained.
A substance that does not conduct heat or electricity.
- ‘The term ‘fuel cell’ was coined by the English chemists Ludwig Mond and Carl Langer to describe their device, developed nearly 50 years later, which used a porous non-conductor to hold the electrolyte.’
- ‘Most other minerals are non-conductors of electricity.’
- ‘They terminate at the surfaces of the conductors under induction, or at the particles of non-conductors, which, being electrified, are in that condition.’
- ‘A non-conductor can be charged by induction by exposure to an electrostatic field that is present on a surface charged with static electricity.’
- ‘Substances such as hydrogen chloride or acetic acid are non-conductors in the pure state but give rise to ions and thus electrical conductivity when dissolved in water.’
