, DEEL 1: BASISELEKTRICITEIT

1.1 Grootheden en Wet van Ohm

Elektrische grootheden:
→ Spanning (U): DRUK op elektronen → Volt (V!)
→ Vergelijking: waterdruk in leiding!
→ Stroom (I): HOEVEELHEID elektronen → Ampère (A!)
→ Vergelijking: waterstroom (liter/min!)
→ Weerstand (R): BELEMMERING stroom → Ohm (Ω!)
→ Vergelijking: kraandiameter (dun = meer weerstand!)
→ Vermogen (P): HOEVEEL energie per seconde → Watt (W!)


Wet van Ohm: U = I × R (KERN formule!)
→ I = U / R (stroom berekenen!)
→ R = U / I (weerstand berekenen!)
→ Voorbeeld: U = 230V, R = 23Ω → I = 230/23 = 10A!


Vermogen: P = U × I (Watt!)
→ P = I² × R (als U niet bekend!)
→ P = U² / R (als I niet bekend!)
→ kWh: kilowattuur (energie = vermogen × tijd!)
→ 2000W × 3 uur = 6 kWh → 6 × €0,40 = €2,40!


→ Gelijkstroom (DC): stroom in 1 richting (batterij, zonnepaneel!)
→ Wisselstroom (AC): stroom wisselt richting (230V, 50Hz → stopcontact!)
→ 50 Hz: 50× per seconde van richting!
→ 230V: effectieve waarde (piek = 325V!)
