making a circuit

-electricity needs to flow.

-it needs to go all the way arround.

-we call de going around of

electrons, electricity. 

why does a cable have a plastic coating? 

insulators and conductors

insulator -> electrical

current does NOT flow

easily.

conductor -> electrical current

DOES flow easily.

switches

a "door" for electrical current

LED

-light emitting diode

-current can only flow one way

-longer to the positive side of the battery

-very efficiënt

measuring current

variable	symbol	unit	symbol
current	I (capital i)	ampère	A

make your own circuits

measure the ampère with the ammeter

use different amounts of batteries.
