Evaporation of the water in the wet bulb fabric cover causes the temperature of the wet bulb to go down. When the air is dry, more water will evaporate, and when the air is saturated, less will evaporate.
because the water causes the temperature to be lower
The wet bulb thermometer is typically read lower than the dry bulb thermometer because the evaporation of water on the wet bulb cools the sensor by removing heat from it. This process is known as evaporative cooling and results in a lower temperature reading on the wet bulb thermometer compared to the dry bulb thermometer.
Bulb temperature is typically lower than dry temperature because the bulb thermometer measures the temperature of the air without factoring in the effects of evaporation. The dry bulb temperature, on the other hand, accounts for the cooling effect of evaporation, giving a lower reading than the bulb temperature.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

Yes, and the 135V bulb will last longer than the 120V bulb because the filament is thicker.The downside is that the higher voltage bulb will not be quite as bright, and its light may be slightly more yellow in color (the color temperature will be less when run on a lower than design voltage).
The brightness of a light bulb is determined by the amount of electrical energy it receives, which affects the intensity of the light produced. A higher wattage bulb will generally be brighter than a lower wattage bulb.
No.
Normal cause is failed bulb.
The wet bulb temperature is always lower than the dry bulb temperature. The wet bulb temperature is the temperature taken by a thermometer covered in a wet cloth and exposed to moving air, and it reflects the evaporative cooling effect.
There is no particular reason why a motor should have a bigger resistance than a bulb. A motor's resistance must depend on what current it draws at the particular voltage it was designed to run on. Equally, a bulb's resistance must depend on what current it draws at the particular voltage it was designed to run on. A particular motor may have a higher resistance than one kind of bulb but that same motor may have a lower resistance than another kind of bulb.
