7Px 14 Whiringa-ā-Nuku 2013What we will do What we will learnPreliminaries and roll The importance of starting
wellUse the website to look at the lesson schedule for this week and this term
How we will be using our time
Extend reactance from capacitors to inductors (zero in DC and finite in AC)
What inductive reactance is, why it exists, what affects it, what the formula is and how to use it.
See the book’s take on the formula
What the formula actually is
Measure the resistance and reactance (actually impedance) of an inductor
How to qualitatively apply new ideas to measurements
HRT, HW marking – and set the due date for some more units
How to use time well and how to plan ahead
7 Physics Homework MarkingNo. of marks
What for
1 Having sketches and FULL working1 Neat presentation and down-page
format1 Answer underlined and units given1 Self marked and all correct –
eventually1 In on time and signed for (“This is
my own work”…….)Total A mark out of five that will contribute to
the “homework” grade in the reports
