7Px 29 Mahuru 20117Px 29 Mahuru 2011What we will do What we will learnPreliminaries and roll. That it is important to start
well
Compare the steady state of an LR DC circuit with the transient start-up situation
That there is a “shake-down” period before things even out
Extend our knowledge yesterday into the transient state using the “blurb” for Unit 7
The importance of the ratio of L to R, the relevance of 37% and 63% and the link between Inductor Voltages and Circuit Currents
Examine the amount of energy stored in an inductor
How to find the amount of stored energy
Set a due date for Unit 7 HW and have some HRT
How to influence our workstream and use time wisely
7 Physics Homework MarkingNo. of marks
What for
1 Having sketches and FULL working
1 Neat presentation and down-page format
1 Answer underlined and units given
1 Self marked and all correct – eventually
1 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
