YR2_T2_LSN6
Topic 2.4 Circuits

Slide 2 - Slide

Plan for today:
  • Explanation T2.4 Circuits
  • Work on Kwizl exercise
  • Make homework 

Slide 3 - Slide

Learning goals
I can…
  • explain the basic components necessary for building a simple circuit.
  • draw circuit diagrams by using the circuit symbols.
  • explain the advantages and disadvantages of a series circuit.
  • calculate the current or voltage at various points in a series circuit.
  • explain the advantages and disadvantages of a parallel circuit
  • calculate the current or voltage at various points in a parallel circuit
  • use an ammeter or voltmeter to properly measure the current or voltage at a certain point in a circuit.

Slide 4 - Slide

Key words
  • wire
  • power source
  • batteries
  • switch
  • lamp
  • bell
  • Volt meter
  • Ammeter
  • motor
  • LED
  • series circuit
  • parallel circuit
  • consumption

Slide 5 - Slide

Basic circuit
Copper wire connects the voltage source to the device and back again. When the switch is closed the electricity can flow through the wire and light the bulb.

Slide 6 - Slide

Drawing a circuit
These symbols make drawing circuits easier

Slide 7 - Slide

Circuits - Series
  • All components are in the same loop, end to end.
  • There is only one direction in which the current can flow.
  • The same current throughout the entire circuit.
  • The voltage is shared by all components within the circuit.

Slide 8 - Slide

Circuits - Series

Slide 9 - Slide

Every ammeter will show the same value.
The voltage is shared by all components.

Slide 10 - Slide

What happens to the voltage when there are more components in a series circuit?
A
every component gets the same voltage
B
one component gets all of the voltage
C
The voltage is shared by all components
D
this won't work

Slide 11 - Quiz

Circuits - Parallel
  • Multiple loops or paths for the current to flow through.
  • The current is divided over every pathway.
  • The voltage is the same for all components.

Slide 12 - Slide

Circuits - Parallel

Slide 13 - Slide

The voltage is the same for all components, 
the current is divided.
The current only divides equally if components are the same.

Slide 14 - Slide

voltage is the same for all components
current is the same throughout circuit
Series
Parallel
Still works if one lamp is broken
If you connect batteries this way, you can add their voltages

Slide 15 - Drag question

Measuring current
Ammeter:  is used to measure the current 
The current is measured in amps (A) 
The ammeter has to be connected in series with the device.

Slide 16 - Slide

Measuring voltage
Voltmeter: is used to measure the voltage
The voltage is measured in volts (V)
The voltmeter has to be connected in parallel to the device.

Slide 17 - Slide

Circuit simulation
Go to Kwizl and complete assignment: Circuits simulation part 1





Slide 18 - Slide

Homework
  • Finish Kwizl assignment: ''Ciruits simulation part 1''
  • Read Topic 2.4 (p. 78-81)
  • Complete the exercise of Topic 2.4 (p.82-87)
  • Study the glossary of Topic 2.4 on StudyGo.
