- 1What is electiricty and its unitsthe flow of electrons (joules)
- 2what is a conductorallows electrons to pass through eg metal
- 3insulatordont allow electrons to pass through eg non metals
- 4Static electricityis due to chare built up (friction) electrons are transferred from one substance to another
- 5gain of electrons...negative
- 6loss of electronspostitive
- 7what is a circutpath in which electrons move from its source
- 8what does the cell dostore chemical energy
- 9series circutconnected one end to end and a simple loop for current to flow
- 10parallel circuitconnected side to side and has multiple routes for current to flow
- 11what is DCcurrent only flows one way
- 12what is ACcurrent changes direction 50 times each second
- 13what is voltagepush on electrons and the measure of difference in electrical energy
- 14power =current X voltage or energy/time
- 15cost of electricty=power X cost 1kw X time
- 16uses of magnetsnavigation motors separation
