Slide 7 - Diapositive

What is current?

= an electrical currents consists of moving charge

Slide 8 - Diapositive

Slide 9 - Vidéo

Current (I)

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

E.g. I = 1,5 A

Slide 10 - Diapositive

Converting Amps

1 A = 1000 mA

1 mA = 0.001 A
