Static electricity & using electric current 0.0 / 5 ? PhysicsElectricityGCSEEdexcel Created by: AmyoungCreated on: 09-02-15 11:49 What is 'transfer of charges? 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. 9 of 9
