Presentation Transcript

  1. Resistors in Series and Parallel Ch. 20 - 2

  2. Resistors : Series • In a series circuit, all components are connected end-to-end, forming a single path for electrons to flow. • When resistors are connected in series, the current in each resistor is the same.

  3. Resistors: Series • Total current in a series circuit depends on how many resistors are present and how much resistance each offers. • The equivalent resistance can be used to find current.

  4. Guided Practice • Open books to pg. 738 • Sample Problem 20A

  5. Resistors : Series • Series circuits require all elements to conduct.

  6. Resistors: Parallel • In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

  7. Resistors: Parallel • The sum of currents in parallel resistors equals the total current. • Resistors in parallel have the same potential differences across them.

  8. Resistors: Parallel • The equivalent resistance must always be less than the smallest resistance in the group of resistors.

  9. Guided Practice • Open books to pg. 743 • Sample Problem 20B

  10. Summary Table pg. 742
