BUILDING ELECTRICAL CIRCUITS BUILDING ELECTRICAL CIRCUITS Presentation Transcript

  • Presentation by: www.sciencetutors.zoomshare.com Series And Parallel Circuits (Understanding The Basics Part 1) BUILDING ELECTRICAL CIRCUITS
  • YOUR TARGET
    • At end of this presentation you should know:
    • The symbols used to draw circuits
    • The basic differences between series and parallel circuits.
    • What happens to the current in series and parallel circuits.
    • The answers to basic question on circuits
    www.sciencetutors.zoomshare.com
  • What are Electrical Circuits?
    • Why is it important to learn about circuits?
    www.sciencetutors.zoomshare.com
  • Why Do we Need Circuits?
    • Remember electricity is a flow of electrons. A complete circuit is needed for electricity to flow
  • CURRENT
    • This is the amount of electricity flowing in a circuit.
    • Remember: the unit of current is Amps and the symbol is (A)
    www.sciencetutors.zoomshare.com
  • TYPES OF CIRCUITS
    • There are basically three types of circuit
    • Series,
    • Parallel, and
    • Series and Parallel circuit
    www.sciencetutors.zoomshare.com
  • QUICK QUIZ
    • What do these symbols show?
    1 2 3 4 5 6 www.sciencetutors.zoomshare.com
  • Circuit Components www.sciencetutors.zoomshare.com
  • Basic Circuit Symbols
    • You should familiarize yourself with these symbols
  • QUICK QUIZ
    • Which of these circuits are parallel circuits and why?
  • Is it Series Or Parallel Circuit?
    • What is difference between parallel and series circuit?
  • YOU SHOULD KNOW
    • The series circuit is a single path for current to flow.
    Notice this, if part of the path for current is obstructed, the lights all go out like Christmas tree lights. www.sciencetutor.zoomshare.com
  • Quick Quiz
    • Which of these statements is correct
    • Series circuits are used for house lights
    • Parallel circuits are used for house lights
  • Look At the Picture below Are the light bulbs in series or parallel?
  • YOU SHOULD KNOW…
    • In a parallel circuit the electricity has several paths that it can travel.
  • QUICK QUIZ
    • Series circuit is a single path for current to flow while parallel circuits have more than one path.
    • What are the disadvantages of connecting lights in series?
    www.sciencetutors.zoomshare.com
  • QUICK QUIZ
    • Which of the switches 1, 2 and 3 must be pressed to make the light bulb X in the circuit come on?
    www.sciencetutors.zoomshare.com
  • You Should Know..
    • The main difference between a series circuit and a parallel circuit is in the way the components are connected.
