Q. The equation to show the relation between resistance and illumination in light dependent resistor can be written as

A
R = A.Ea
B
R = A.E/a
C
R = A.E^a
D
R = A.2Ea
Solution:

The equation to show the relation between resistance and illumination can be written as
R = A.E^a
where E ?llumination (lux)
R ?esistance (Ohms)
A,a ?onstants
The value of ??epends on the CdS used and on the manufacturing process. Values usually range between 0.7 and 0.9
