  1. UNIT FIVE: Electricity and Magnetism • Chapter 16 Electricity • Chapter 17 Magnetism

  2. Chapter Sixteen: Electricity • 16.1 Charge and Electric Circuits • 16.2 Current and Voltage • 16.3 Resistance and Ohm’s Law • 16.4 Types of Circuits

  3. Chapter 16.1 Learning Goals • Define static electricity and discuss its causes. • Explain what it means when an object is electrically charged. • Describe the components of an electric circuit and explain the difference between a closed circuit and an open circuit.

  4. Key Question: What is static electricity? Investigation 20C Electric Charge

  5. 16.1 Positive and negative charge • Electric charge, like mass, is also fundamental property of matter. • Inside atoms found in matter, attraction between positive and negative charges holds the atoms together.

  6. 16.1 Positive and negative charge • Whether two charges attract or repel depends on whether they have the same or opposite sign. • A positive charge attracts a negative charge and vice versa. • Two similar charges repel each other.

  7. 16.1 Electrical forces • The unit of charge is the coulomb (C). The name was chosen in honor of • Charles Augustin de Coulomb (1736-1806), the French physicist who performed the first accurate measurements of the force between charges.

  8. 16.1 Static charge • A tiny imbalance in either positive or negative charge on an object is the cause of static electricity.

  9. 16.1 Electric current • Electric current is caused by moving electric charge. • Electric current comes from the motion of electrons. current

  10. 16.1 Electric Circuits • Wires in electric circuits are similar in some ways to pipes and hoses that carry water.

  11. 16.1 Circuit diagrams • When drawing a circuit diagram, symbols are used to represent each part of the circuit.

  12. 16.1 Circuit diagramsand electrical symbols • Electrical symbols are quicker and easier to draw than realistic pictures of the components.

  13. 16.1 Resistors • A resistor is an electrical device that uses the energy carried by electric current in a specific way. • Any electrical device that uses energy can be shown with a resistor symbol.

  14. 16.1 Open and closed circuits • Current only flows when there is a complete and unbroken path, or a closed circuit. • Flipping a switch to the “off” position creates an open circuit by making a break in the wire.

  15. 16.1 Open and closed circuits • Switches are used to turn electricity on and off. • Flipping a switch to the off position creates an open circuit by making a break in the wire.
