Module 3 - Identification and specification of electrical components - Electrical workshop

 
Module 3:

Dear Students,
Below is the list of information you need to know from Module 3 of electrical workshop.

  • 9 basic electrical components from Module 3
    • lamp - light indicator
    • motor - motion indicator
    • buzzer - sound indicator
    • resistor - limit the flow of current
    • variable resistor -  adjust or control the flow of current
    • LDR - light dependent resistor - resistance changes with light intensity
    • capacitor - used to store electrical charge
    • inductor - used to store magnetic field 
    • diode - lets current flow in one direction only
  • You should know the function and uses of all the electrical components
  • Resistor color code
  • BBROY from Great Britain has a Very Good Wife
  • Capacitor color code, you should understand the 3 numbers written on capacitors and determine the value of the capacitors from there.
  • End of chapter questions and answers.
