, DEEL 1: BASISELEKTRICITEIT

1.1 Spanning, Stroom en Weerstand

Spanning (U): drukverschil → DRIJFT stroom aan (volt, V)
→ Vergelijk: waterdruk in leiding
→ Stopcontact NL: 230V (wisselspanning 50Hz)


Stroom (I): beweging van elektronen (ampère, A)
→ Vergelijk: hoeveelheid water die stroomt
→ Gevaarlijk vanaf ~30mA (hartfalen!)


Weerstand (R): tegenstand tegen stroom (ohm, Ω)
→ Vergelijk: vernauwing in leiding
→ Hoge weerstand = minder stroom


Wet van Ohm:
U = I × R
I = U / R
R = U / I


→ 230V, 23Ω weerstand → I = 230/23 = 10A


Vermogen (P):
P = U × I (watt, W)
P = I² × R
P = U² / R


→ 230V × 10A = 2300W = 2,3 kW
→ kWh = verbruik over tijd (1 kW × 1 uur = 1 kWh)
→ Energierekening: prijs per kWh × verbruik
