  • Performing calculations on series and parallel network of resistors using Ohm`s law.
  • Applying Kirchoff`s laws to various networks.
  • Performing basic capacitor calculations relating to transients.
  • Performing basic transformer calculations. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that a learner will be competent in:
  • Communication at NQF Level 2.
  • Mathematics at NQF Level 2. 

  • UNIT STANDARD RANGE 
    Basic theories include but are not limited to elementary key concepts in electronics.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
