When electrons arer transferred from one material to the other
1 of 9
Which charges attract, and which repel?
Opposute charges attract, like charges repel
2 of 9
Name some dangers of static electricity
Lightening, explosion in fuel from a spark on fuel nozzle
3 of 9
What is earthing
When electrons flow to earth through an object or the other way round
4 of 9
What is electrostatic phenomena
Charging by induction - neutral objects attracting/repelling other charges e.g balloon and wall
5 of 9
Potential difference
Also called voltage, across an electrical component is needed to make a current flow through it.
6 of 9
What does the equation [P = I x V] mean?
Use of power = current x potential difference
7 of 9
What does the equation [E = I x V x t] mean?
Energy transferred = current x potential difference x time
8 of 9
What is resistance?
There is a resistance to the flow of an electric current through most conductors.
