P2 Topic 1: Static and Current Electricity
Cards in this deck (16)
- 1List the particles found in an atomProtons, Neutrons and Electrons
- 2Identify the mass and charge of an electonMass is almost zero
Charge is -1 - 3Identify the mass and charge of a protonMass is 1
Charge is 1 - 4Identify the mass and charge of a neutronMass is 1
Charge is 0 - 5Explain how an insulator is chargedRubbing the insulator caused friction which transfers electrons onto, or from, the object.
- 6State the charge on an object that has gained electronsNegative
- 7State the charge on an object that has lost electronsPositive
- 8Describe the interaction between like charges e.g. positive - positive or negative - negativeRepel
- 9Describe the interaction between unlike charges e.g. positive - negativeAttract
- 10Explain the process of earthingEarthing removes excess charge by allowing electrons to flow onto or from an object
- 11Explain the advantages of electrostatic paint sprays and insecticide spraysThe droplets have like charges so they repel and spread out.
It will also be attracted to uncharged objects.
- 12Describe the dangers of electrostatic charges when refuelling a vehicleA spark can ignite the fuel causing an explosion
- 13Identify the units of charge
- 14Define electric currentThe rate of flow of charge
or
The flow of electrons
- 15Identify the type of current supplied by cells and batteriesDirect current
- 16Define the term direct currentThe movement of charge in one direction only
