What we will do What we will learn 13Px 06 Mahuru 2017 Preliminaries and roll How to kick off well “Wake up” our knowledge of Electromagnetism to date and resume our work towards the End Of Topic Test AND the 20th of November How to make great use of time. 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.
