Question | Answer |
What is electiricty and its units | the flow of electrons (joules) |
what is a conductor | allows electrons to pass through eg metal |
insulator | dont allow electrons to pass through eg non metals |
Static electricity | is due to chare built up (friction) electrons are transferred from one substance to another |
gain of electrons... | negative |
loss of electrons | postitive |
what is a circut | path in which electrons move from its source |
what does the cell do | store chemical energy |
series circut | connected one end to end and a simple loop for current to flow |
parallel circuit | connected side to side and has multiple routes for current to flow |
what is DC | current only flows one way |
what is AC | current changes direction 50 times each second |
what is voltage | push on electrons and the measure of difference in electrical energy |
power = | current X voltage or energy/time |
cost of electricty= | power X cost 1kw X time |
uses of magnets | navigation motors separation |
