We’ve been looking at the different properties of series and parallel circuits over the past week or so.  Since there are only 91 days left until Christmas, I thought I would ask you all for some shopping advice.

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.

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.

We looked at different types of lamp today, including filament lamps, neon & argon lamps, mercury vapour lamps, sodium lamps and fluorescent tube lights.
The wikipedia site has lots of information about different types of light.

See if you can find out how a halogen lamp works.
