Tabel: Voorbeeld (aanvaar ander voorstelle deur leerder)

Funksie Toestelle Werking as 'n sisteem
Warmte
Verwarmer Element (metaal) word warm vanweë weerstand teen stroom wat vloei, energie kom vry in vorm van warmte. Kan olie of water verwarm.
Oond Soos bg. maar in ‘n houer om hitteverlies te voorkom.
Stoofplaat Element wat ‘n plat oppervlak vorm waarop kastrolle/ potte/panne kan staan en met hitte in kontak kom om verkies te beperk.
Broodrooster, ketel, strykyster, ens.
Lig
Warm gloeilampe Bevat element wat gloei in houer met gas wat voorkom dat dit uitbrand.
Buislig met twee pole waar elektrisiteit deur gas beweeg Word nie baie warm nie, dus min verlies aan hitte.
Flits van kamera.
Beweging
Stofsuier Elektrisiteit laat motor bestaande uit drade en magnete beweeg, wat suigkrag laat ontstaan.
Grassnyer, boor, klitser, waaier is ander voordele.
Klank
Radio Elektrisiteit word gebruik om radiogolwe op te vang en na klankgolwe om te sit wat deur luidspreker uitgestuur word.
Alarmstelsels, wekkers, TV, - soortgelyk.

Inhoud

Aktiwiteit: om die gebruike van elektriese energie te kan beskryf [lu 2.1]

  • Eskom is Suid-Afrika se grootste verskaffer van elektrisiteit en hul mikpunt is om jaarliks honderde “nuwe” skole, hospitale, huise, ens. van elektrisiteit te voorsien.
  • Die vier gebruike van elektrisiteit wat ons die meeste aanwend, is warmte, lig, beweging en klank.
  • Dink aan elektriese toestelle wat warmte, lig, beweging en klank aan ons verskaf. Kies twee vir elkeen van die gebruike. Doen navorsing om by elkeen te bepaal hoe elektriese energie gebruik word om die funksie te verrig waarvoor hulle aangewend word (met ander woorde hoe elkeen as ‘n sisteem funksioneer).
  • Voltooi die onderstaande tabel deur die inligting wat jy versamel het daarin uiteen te sit. Maak seker dat jy in elke groep 'n verskeidenheid toestelle kies (byvoorbeeld nie net verskillende stowe vir warmte nie).

lack electricity and its more savely than electronic microscope because its naturally by using of light
Abdullahi Reply
advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
