Textbook Question
Chapter 3, Problem 59P
- Using the characteristics of Fig. 3.38, determine the resistance of the photoconductive cell at 10 and 100 foot-candles of illumination. As in Problem 58, note that it is a log scale.
- Does the cell have a positive or a negative illumination coefficient?
- Is the coefficient a fixed value for the range 0.1 to 1000 foot-candles? Why?
- What is the approximate rate of change of R with illumination at 10 foot-candles?
