Electricity Ideas

Electricity Ideas:
I'd like to discuss the electricity/pressure/flow analogies with the AC/energy transfer discussion.

Batteries -series/parallel - this could develop into a nice inquiry-based lesson also

nice discussion here,

good discussion on battery capacities (why you shouldn't mix types) - http://www.zbattery.com/seriesparallel.html

Transformers:
We should be able to create transformers in class now for the students which might be a great inquiry based lesson.  The XK-150 should be able to do this just fine provided we get all the hardware in on time.  We can even create DC current from AC if you want - I can create a lesson.
