1 What we will do What we will learn 13Px 07 Mahuru 2017
Preliminaries and roll How to kick off well Mark the HW that was due yesterday How well we understood the inductor, self inductance and EMF If time, move on to Voltages and Currents for inductors – on startup and shutdown How “transients” behave and why 37% is important to remember (e to the -1) Examine the energy stored in the magnetic field of an inductor How much energy is stored AND how to recognize equations for energy. Set new HW, set a due date and have HRT How to make great use of time.

2 HW item Skills practiced Elex: Pages 184 - 185
Due Tuesday, the 22nd of Aug 2017 Revision of NCEA2 magnetism and also intro to idea of flux Elex: Pages Faraday’s Law Elex: Pages Lenz’s Law Elex: Pages Due Tuesday, the 5th of Sept 2017 Transformers Elex: Pages 196 Self-Inductance, the inductor and back EMF Elex: Pages Due Friday, the 15th of Sept 2017 Transient currents and voltages in LR DC circuits Elex: Pages Inductors in DC circuits

3 Homework Marking No. of marks What for 1
Having sketches & FULL working for all Neat presentation and down-page format Answer underlined and units given Self marked and all correct – eventually 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
