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)

Insulator
Conductor

Slide 6 -Sleepvraag

Measuring current

Slide 7 -Tekstslide

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

Slide 9 -Video

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

E.g. I = 1,5 A

Converting Amps
1 A = 1000 mA

1 mA = 0.001 A
