What we will do What we will learn 13Px, Ko te Rāmere, 02 Mahuru 2016
Do Now: Get our mechanics papers back and check Mr H’s counting That nobody has checked Mr H’s counting yet. Move on to the post-mortem on Mechanics How to strengthen what we know and fill any gaps that exist If time, revisit Faraday’s Law and then extend it to self-inductance What inductance does to a DC circuit on startup If time, examine mutual inductance and how this is a big player in the electricity distribution network – especially with respect to minimisation of heat losses What a transformer is, what it does and WHY it is used If time, examine the cases when a transformer is a good idea Why humans use transformers
