photoresistorn.

Brit.

/ˌfəʊtəʊrᵻˈzɪstə/, U.S.

/ˌfoʊdoʊrəˈzɪstər/,

/ˌfoʊdoʊriˈzɪstər/

Origin: Formed within English, by compounding; perhaps modelled on a German lexical item. Etymons: photo- comb. form, resistor n.

Etymology: < photo- comb. form + resistor n., perhaps after German Photowiderstand (1937 or earlier; now Fotowiderstand ). Compare earlier photoresistance n.

Physics.

A resistor whose resistance varies according to its degree of illumination.
