DC Circuits Week 1

I think art is not an ornament or refinement at the fringes of human intelligence, I think it’s at the center. It’s at the core. Robert Pinsky

Each Week the work delivered is in keeping with the syllabus from training.gov.au and either at the front of the week of delivery there will be a list of the topics to be covered and or a link to a lesson plan showing the relevant topics.

The first couple of weeks cover these topics as shown below. These topics are taken from Training.gov.au … there is a link to this on the home page of our web site. Training.gov is the official site for maintaining the Australian training packages and all training organisations must follow the criteria as specified.

T1 Basic electrical concepts encompassing:

electrotechnology industry
static and current electricity
production of electricity by renewable and non renewable energy sources
transportation of electricity from the source to the load via the transmission and distribution systems
utilisation of electricity by the various loads
basic calculations involving quantity of electricity, velocity and speed with relationship to the generation and transportation of electricity.

T2 Basic electrical circuit encompassing:

symbols used to represent an electrical energy source, a load, a switch and a circuit protection device in a circuit diagram
purpose of each component in the circuit
effects of an open-circuit, a closed-circuit and a short-circuit
multiple and sub-multiple units

T3 Ohm’s Law encompassing:

basic d.c. single path circuit.
voltage and currents levels in a basic d.c. single path circuit.
effects of an open-circuit, a closed-circuit and a short-circuit on a basic d.c. single path relationship between voltage and current from measured values in a simple circuit
determining voltage, current and resistance in a circuit given any two of these quantities
graphical relationships of voltage, current and resistance
relationship between voltage, current and resistance

T5 Effects of electrical current encompassing:

physiological effects of current and the fundamental principles (listed in AS/NZS 3000) for protection against the this effect
basic principles by which electric current can result in the production of heat; the production of magnetic fields; a chemical reaction
typical uses of the effects of current
mechanisms by which metals corrode
fundamental principles (listed in AS/NZS3000) for protection against the damaging effects of current
