AS3.6 Electricity (External)

This external standard is worth 6 credits. You will require basic knowledge from L2 electricity to do well here. Assessment is limited to a selection from the following:
Resistors in DC Circuits

Internal resistance; simple application of Kirchhoff’s Laws.

Capacitors in DC Circuits
Parallel plate capacitor; capacitance; dielectrics; series and parallel capacitors; charge/time, voltage/time and current/time graphs for a capacitor; time constant; energy stored in a capacitor.

Inductors in DC Circuits
Magnetic flux; magnetic flux density; Faraday’s Law; Lenz’s Law; the inductor; voltage/time and current/time graphs for an inductor; time constant; self inductance; energy stored in an inductor; the transformer.

AC Circuits
The comparison of the energy dissipation in a resistor carrying direct current and alternating current; peak and rms voltage and current; voltage and current and their phase relationship in LR and CR series circuits; phasor diagrams; reactance and impedance and their frequency dependence in a series circuit; resonance in LCR circuits.
