Principle objective of this lecture is to present on Static Electricity. Static Electricity when a material has an excess or a lack of electrons. To understand static electricity, we have to learn a little bit about the nature of matter. Example: A glass of water kept at room temperature long enough will become empty because water molecules slowly leak through the walls of the glass. water molecules move into the air as gas molecules. water left in a glass starts to boil and becomes a gas. water slowly combines with oxygen to become carbon dioxide.
