Specific Outcomes and Assessment Criteria: 
SPECIFIC OUTCOME 1 
Perform calculations on series and parallel circuits. 
ASSESSMENT CRITERIA 
ASSESSMENT CRITERION 1 
Calculations are performed to simplify the total resistance of the network. 
ASSESSMENT CRITERION RANGE 
Calculations refer to calculations done on series, parallel, combination resistive, capacitive and inductive circuits. 
ASSESSMENT CRITERION 2 
Calculations are performed in series, parallel and combination circuits that consist of cells only to determine the potential differences. 
SPECIFIC OUTCOME 2 
Perform calculations using Ohm's law. 
ASSESSMENT CRITERIA 
ASSESSMENT CRITERION 1 
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 
Electromotive 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 CRITERION 1 
Voltage and current dividers are described in terms of Kirshoff's Laws. 
ASSESSMENT CRITERION RANGE 
The description must include the current and voltage laws. 
ASSESSMENT CRITERION 2 
Calculations are performed between applied voltage and voltage drops in closed circuits. 
ASSESSMENT CRITERION 3 
Calculations are performed between input current versus output current in closed circuits. 
SPECIFIC OUTCOME 4 
Perform basic impedance, capacitive reactance and inductive reactance (RLC) calculations. 
ASSESSMENT CRITERIA 
ASSESSMENT CRITERION 1 
RL and RC circuits are calculated inclusive of phasor diagrams to determine the total impedance.

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.
