D. Phosphorous
Answer:A
Explanation: The resistance of the photoconductive cell in darkness is typically in the order of 100kΩ. 9. Which material is used for photoconductive cells?
A. Germanium B. Cadmium sulphide C. Lithium D. Phosphorous
Explanation: The conductivity in cadmium sulphide is a function of incident radiant energy. So, it is used for photoconductive cell. 10. Name the resistive transducer that varies its resistance on application of external stress?
