Slide 5 - Tekstslide
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 - Tekstslide
Drawing a circuit
These symbols make drawing circuits easier
Slide 7 - Tekstslide
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 - Tekstslide
Circuits - Series
Slide 9 - Tekstslide
Every ammeter will show the same value.
The voltage is shared by all components.
Slide 10 - Tekstslide
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 - Quizvraag
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 - Tekstslide
Circuits - Parallel
Slide 13 - Tekstslide
The voltage is the same for all components,
the current is divided.
The current only divides equally if components are the same.
Slide 14 - Tekstslide
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 - Sleepvraag
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 - Tekstslide
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.
