I need a new set of Christmas tree lights.  Should I be in the market for a set of lights built in series or parallel?  Don’t forget to tell me what information influenced your choice!

If you’re not sure why the series/parallel decision would make a difference to tree lights, you might want to check this site.  There’s also some information on series and parallel circuits here.

S3 Homework – AC/DC

Homework for 15 September is to complete the problems on page 7 of the homework booklets I gave out on Tuesday. We have recently reviewed AC & DC as part of the traffic lighting exercise, so you should be able to tackle these without too much difficulty.
