van Ohm se wet • Stroom in serie bly konstant by elke punt.
• Ohm se wet = die elektriese potensiaalverskil (V) • Selle wat in parallel verbind is produseer almal dieselfde
tussen twee punte in 'n stroombaan is gelyk aan stroom as een sel.
die produk van die stroom (I) tussen daardie
punte en die totale weerstand (R) van al die
elektriese komponente in die stroombaan.
• V = I x R.
• Verhoogde stroom veroorsaak verhoogde E1: Elektriese Gloeilampe in serie en parallel

• Stroom = die gerigte vloei van elektrone deur 'n en parallel (OF-logika)
stroombaan.
• 'EN'-konfigurasie - skakelaars wat in serie verbind is.
• Elektrone = negatief gelaaide partikels.
• 'OF'-konfigurasie - skakelaars wat in parallel verbind is.
• Stroom vloei van positief na negatief in 'n
konvensionele stroombaan.
• Elektriese energie word gedra deur bewegende
elektrone.
• Elektrone in GS beweeg in een rigting.
• Elektrone in WS beweeg in een rigting en terug in die
teenoorgestelde rigting.
