Elektriciteit~nask 1
grootheid symbool eenheid
stroomsterkte I A
spanning U V
vermogen P W, kW en J/s
weerstand R Ω
tijd t h en s
energie E kWh en J
windingen N -
W = J/s :1000 kW
kWh x3 600 000 J
TJ x1000 GJ x1000 MJ x1000 KJ x1000 J
h x60 min x60 s
P=U x I E=P x t R=U/I
η betekend rendement, eenheid altijd in %
η=(Paf / Pop) x100 Paf= nuttig afgeven Pop= totaal opgenomen
η=(Eaf / Eop) x100
Serieschakeling:
- Stroomsterkte overal hetzelfde
- Spanning word verdeeld
Grootste weerstand=meeste spanning
Serie: It=I1=I2 Ut=U1+U2
Parallelschakeling:
- Spanning overal hetzelfde
- Stroomsterkte splitst
Grootste weerstand=minste spanning
Parallel: It=I1+I2 Ut=U1=U2
Transformator= Np/Ns = Up/Us p= primaire s= secundaire
Allebei de verhoudingen zijn even veel. Dus als er links x3 is aan de andere kant
ook x3.
Ideale transformator= Ps=Pp
