Question

What type of electrical device used a "Cat's Whisker".

Answer 1

The "cat's whisker" is a type of electrical device that was used in the early days of radio. It was a thin wire that was placed against a crystal, such as galena, in order to detect radio signals. The device was used to tune radios and other electrical equipment.

Answer 2

radio receivers

devices such as the “cat whisker” detector, which was composed of a fine wire (the whisker) in delicate contact with the surface of a natural crystal of lead sulfide (galena) or some other semiconductor material.

Answer 3

A "Cat's Whisker" was used in early crystal radios as a primitive semiconductor diode to detect radio signals. Radio signals help us to hear what is being communicated.
