What happens to the resistance of an LDR when light increases?

Here are the answers to the questions:

3.7) When light increases, the resistance of an LDR (Light Dependent Resistor) decreases.

3.8) When temperature increases, the resistance of a negative temperature coefficient (NTC) thermistor decreases.

3.9) A touch sensor could be used in a touchscreen or a touch lamp. A moisture sensor could be used in an automatic irrigation system for plants.

3.10) The main function of a capacitor in a circuit is to store electrical energy in an electric field.
