  1. Electricity Introduction

  2. What is Electricity? • Movement of electrically charged particles • Moves as a current • Current is how fast or how slow it follows a pathway from point a to point b • Will always move from the negative object (more electrons) to the positive (less electrons) because positives attract negatives

  3. No charges are created or destroyed • How does an atom get a charge? • Loses an electron • Law of electric charges • Like charges repel • Opposite charges attract • No charges are created or destroyed

  4. How do electric charges move? • Friction: • two objects are touching and in motion • electrons are wiped from one to another • steals electrons • Conduction: • electrons move by direct contact • Electrons are transferred from more to less • Induction: • electrons move without direct contact • one object is charged • rearranges the charge in the other object

  5. Two types of Electricity • Static electricity: electric charge at rest. Electrons are stored on an object • Current electricity • Two Types of Materials • Conductor: charges can move easily through • Insulator: charges cannot move easily through
