1 7Px 22 Whiringa-ā-Nuku 2013 What we will do What we will learn Preliminaries and roll The importance of starting well See the link between frequency and current (all else being equal) Where the “bell curve” comes from Look at how to minimize impedance and (therefore) maximise current How to “balance the load” Extend the above to industrial Power Factor Correction How to make the phase angle as small as possible See the reprise of resonance How bridges and “The Edge” are linked Set some HRT, check our website schedule and revisit our time plan between now and 25 November How to make the best possible use of time.
