Pages 1 And 2 Flashcards
What is static electricity
Is the build up of charge due to the movement of electrons from one material to another
Protons table
Protons - positive - nucleus
Neutron - neutral - nucleus
Electron - negative - orbital shells
Current electricity
Charge flowing through a wire at a steady weight
Conductor
Material that allows charge through
Insulator
Material that doesn’t allow charge through
Where are convention batteries found
Remotes
What are conventional batteries called in physics
Cells
2 or more cells =
Battery
All metals are conductors as well as
Graphite and carbon
Metals contain
Free electrons which move through a material proving a flow of charge
2 facts about series sercuit
Has only 1 route to flow through
More bulbs added = bulbs get dimmer
2 facts about parallel sercuit
Multiple routes for current to flow through
More bulbs added = bulbs stay same brightness
More cells=
More energy and brigher bulbs
3 examples of an insulator
Wood
Glass rod
Polythene rod
3 examples of a conductor
Paper
Iron nail
Copper wire
What objects use series
Fridge
Bulb
Freezer
What things use parallel
Car lights
Christmas tree lights
Wiring system of a house
