The intensity of light incident on a light dependent resistor (LDR) can vary both its electrical resistance R and the number of charge carriers per unit volume n. The light intensity on an LDR is increased.
Which row of the table describes the effect on R and n?
R | n | |
A | decreases | decreases |
B | decreases | increases |
C | increases | decreases |
D | increases | increases |
