This thought gets you curious, so you want to see if you can find some areas where static electricity is useful to people. This lesson will explain some useful applications of static electricity. So, let's start learning. There are a number of beneficial uses for static electricity, as well as methods to avoid some dangers that can be caused by it. Let's look at some of these uses.
Factories use static electricity to reduce pollution coming from their smokestacks.
They give the smoke an electric charge. When it passes by an electrode of the opposite charge, most of the smoke particles cling to the electrode. This keeps the pollution from going out into the atmosphere. Some people purchase what are called air ionizers to freshen and purify the air in their homes. They work on a similar principle as the smokestack pollution control.
