Slide 4 - Diapositive

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 5 - Diapositive

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 6 - Diapositive

Circuits - Series

Slide 7 - Diapositive

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

Slide 8 - Diapositive

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 9 - Diapositive

Circuits - Parallel

Slide 10 - Diapositive

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

Slide 11 - Diapositive

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 12 - Question de remorquage

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 13 - Diapositive

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 14 - Diapositive

Circuit simulation
