4.1
Making
an 
electrical
circuit

Slide 1 - Tekstslide

Electricity?

Slide 2 - Woordweb

You need a closed circuit to let an electronic device work

Slide 3 - Tekstslide

Electrical circuit
  • a voltage source (supplies electrical energy)
  • connections (carries electrical energy)
  • device(s) (consume electrical energy)

Slide 4 - Tekstslide

Conductors

Substances that electrical currents can flow through easily
Insulators

Substances that do not allow electrical current to pass through them (or only very poorly)

Slide 5 - Tekstslide

Insulator
Conductor

Slide 6 - Sleepvraag

Measuring current

Slide 7 - Tekstslide

What is current?
= an electrical currents consists of moving charge

Slide 8 - Tekstslide

Slide 9 - Video

Current (I)
is a variable (something we can measure) and is measured in Ampere (A).

E.g. I = 1,5 A

Slide 10 - Tekstslide

Converting Amps
1 A = 1000 mA

1 mA = 0.001 A
