3) A light sensing circuit uses a LDR in series with a 22 k2 resistor. The resistance value of the LDR depends upon the light level that it is exposed to. The resistance of the LDR at certain light levels is as follows: At 100 Lux = 1.1 k At 50 Lux = 27 k At 25 Lux = 82 ΚΩ a) Calculate the output voltage VouT at each light level when the components are connected as shown in diagram below:
