Understanding Electricity: The Basics of Atomic Charges and Energy Transfer

This overview introduces fundamental concepts of electricity, focusing on atomic structure and charge transfer. An atom consists of protons, neutrons, and electrons, where protons carry a positive charge, electrons carry a negative charge, and neutrons are neutral. Electricity is defined as energy from moving electrons. Charges are transferred through work done on materials, like rubbing them together, creating ions. The principles of static electricity, such as lightning and everyday phenomena like leather car seats, exemplify these concepts.

Presentation Transcript

  1. Electricity Day 1

  2. Atomic Review An atom consists of 3 particles: • Protons-positively charged • Neutrons-no charge • Electrons-negatively charged

  3. What is Electricity? • A form of energy caused by moving electrons.

  4. How charges act • Like charges repel • Opposites charges attract • Electrons flow from a negatively charged area to a positively charged area

  5. Most objects are electrically neutral

  6. How are charges transferred? • When you rub two substances together you do work and thus you add energy. • This removes electrons from one substance and adds it to the other. • This creates IONS which are charged particles.

  7. Static Electricity • Lightning • Leather car seats • Ben Franklin and the kite. • Sliding your feet on a rug

  8. Electrical Charge • Can be Transferred. • It cannot be created or destroyed.

  9. Summary The energy used to rub two things together is the energy that gets involved in removing and transferring electrons.
