Slide 3 - Tekstslide

§2.4 - Learning Goals:
P. 78-87
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 5 - Tekstslide

§2.4 - Circuits

Slide 6 - Tekstslide

§2.4 - Circuits

Slide 7 - Tekstslide

§ 2.4 - 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

§2.4 Circuits - Series

Slide 9 - Tekstslide

Every am-meter 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

§ 2.4 - 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

§2.4 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

§2.4  - Circuits - Measuring
  • You can measure Current (A) with an am-meter.
  • You can measure Voltage (V) with a voltmeter.
  • You can measure both with a multimeter.

Slide 16 - Tekstslide

Slide 17 - Tekstslide

Am-meter
  • Measuring current

  • Current must run through the meter.
  • The meter is WITHIN the circuit

(The amount of electrons pass through the wire every second, is the amps.)

Slide 18 - Tekstslide

The voltmeter is always connected parallel.
Voltmeter has no influence on the current though the component.

Slide 19 - Tekstslide

A voltmeter
A
must be parallel with the component
B
Must be in series with the component

Slide 20 - Quizvraag

What is the value
of this voltmeter?
A
2,5 volt
B
25 volt
C
12,5 volt
D
0 volt

Slide 21 - Quizvraag

Single loop circuit
conventional
current
Current from the positive terminal to the negative terminal
series circuit
Digital ammeter
Analog Ammeter

the battery has a voltage of 5 V
How much volt is there for a lamp?
A
2.5 V
B
10 V
C
