- 1. ELECTRICITY
- 2. One of the most useful scientific breakthroughs is the development of electric circuits. Electric circuits allow the flow of electric current, which in turn allows you to do things such as cooking, washing clothes, communicating, and transporting goods faster and easier.
- 3. Charges of Subatomic Particles - All matter is made up of a substance called atom. - Atom is the basic unit of element. - It consists of smaller particles known as neutrons, protons and electrons. - Nucleus is the center of the atom.
- 4. - Neutrons are the neutral particles. - Protons are the positively charged particles. - Electrons are the negatively charged particles. - Electrons and protons are surrounded by an invisible force called ELECTRIC FIELD.
- 5. FREE ELECTRONS - The particles surrounding the center of the object is electron. - The outermost shell or orbit holding only one particle is known as valence shell.
- 6. - ELECTRIC CURRENT is the flow or motion of electrons through the material. - CONDUCTORS this are the metals and other materials that possess plenty of free electrons allow the smooth flow of electric current. - INSULATORS are materials like glass, plastic, rubber, and wood, which resist the flow of electric current and have a few free electrons.
