  • 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.

    Ohm's law is defined in terms of the relationship between current, voltage and resistance in closed circuits. 

    ASSESSMENT CRITERION 2 
    Calculations are performed to determine unknown quantities when two of the quantities in a circuit are known. 
    ASSESSMENT CRITERION RANGE 
    Quantities refer to resistances, voltage, power and current within closed circuits.
     

    ASSESSMENT CRITERION 3 
    Electro-motive force, potential difference and internal resistances are calculated to determine the unknown quantity if two of the quantities in a circuit are known. 

    ASSESSMENT CRITERION 4 
    Formulae for Ohm's law and resistivity are transposed to solve for an unknown quantity. 

    SPECIFIC OUTCOME 3 
    Perform calculations using Kirchoff`s laws. 

    ASSESSMENT CRITERIA

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    RL and RC circuits are calculated inclusive of phasor diagrams to determine the total impedance. 
    ASSESSMENT CRITERION RANGE 
    RL and RC circuits refer to both parallel and series circuits.
     

    ASSESSMENT CRITERION 2 
    Calculations are performed in order to determine different variables. 
    ASSESSMENT CRITERION RANGE 
    Different variables include but are not limited to values, voltage, current, capacitors, resistors and impedance.
     

    ASSESSMENT CRITERION 3 
    Charge is calculated from given values of capacitance, applied voltage, live current, and time. 

    SPECIFIC OUTCOME 5

    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.
