Transcript of 7 Px 21 Whiringa - ā- Nuku 2013
7Px 21 Whiringa-ā-Nuku 2013What we will do What we will learnPreliminaries and roll The importance of
starting wellLook at resistance, reactance and impedance
What impedance is, what it is measured in and how to find it.
Extend LR and CR circuits to LCR circuits
How inductors, capacitors and resistors work together in a series circuit AND how their voltages and impedances combine
HRT and HW marking (AC units 1 – 6)
How to handle AC questions
7 Physics Homework MarkingNo. of marks
