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

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
