Q

Stel Ohm se Wet

A

Stroom deur ‘n geleier is direk eweredig aan die potensiaalverskil oor die geleier by ‘n konstante temperatuur.
R=V/I

Q

Ammeter

A
  • meet stroomsterkte in ampere
  • lae weerstand en word in serie geskakel
  • as in parallel geskakel word sal die grootste deel van die stroom deur die ammeter vloei agv sy lae weerstand

Q

Voltmeter

A
  • meet die potensiaalverskil in volt oor ‘n komponent
  • hoë weerstand word in parallel geskakel
  • indien in serie geskakel word sal baie min stroom deur daardie tak vloei

Q

Resistors in parallel geskakel

A
  • potensiaalverskil oor beide is dieselfde, al verskil hulle weerstand
  • stroomverdelers

Q

Faktore wat die weerstand van ‘n resistor bepaal

A
  • die aard van die materiaal wat gebruik word
  • die lengte van die geleier
  • die deursnee van die geleier
  • die temperatuur van die geleier (hoe hoër die temp, hoe hoër die weerstand)
