Light bulbs are available in
many different sizes, wattage and styles. Almost all light bulbs get
hot, some more and some less. Heat of light bulb may be high enough
to cause fire. A piece of paper or cotton cloth next to a hot light
bulb is a recipe for disaster.
Heat of light bulbs are often high
enough to be used as heat source.
Do all light bulbs produce the
same amount of heat? Does the size of light bulb affect the heat it
produces? Does the wattage of a light bulb affect the heat it produces?
These are all possible questions that may be studied.
In this project you will study the
effect of wattage on the heat a light bulb produce.
