Hurrahhhhh ..all the work for the prelims completed ..despite the snow !!!!! :-)
So into revision mode next cycle once we have done more of the questions you were working on in class today.
Don't forget to complete the homework sheet I gave you for Tuesday.
You are working so hard and so well.....you all deserve a pat on the back..or maybe an orange ...we shall see
Have a good weekend

Hi
Great experiments today....they both worked !!!! well for some people blowing a fuse in the power pack did cause a wee problem....
Don't forget fuse sizes and the difference between ac and dc.
Next lesson we shall look at what ac and dc look like on the oscilloscope and how we can compare the peak ac voltage with dc.
Don't forget to do your homework which is due on Friday..no late submissions...
Hope the journey home wasn't too cold.
Come and talk to me if you have any problems.

New topic started....and we did pages 1 to 4 and page 7 plus questions 3,4 and 9 on page 14
Homework is the handout sheets I gave you....please do not give me the answers on the handout sheet....do them properly on paper. Don't forget to show all your working.

Wednesday 1st December 2010
Well done to those of you who got in to school.
For those of you who missed class here is what we did...please do the work - solutions will be issued next class.
Read the theory of potential dividers - page 31.... ...they are also known as voltage dividers. Check your data book the equation is in there - page 3 second column ....
The bigger the resistor the bigger the chunk of voltage that you will measure across it.
Try the example on page 33 the answer is 8 V.
For next lesson ...
1. Complete the questions on pages 28 to 30 (nos 1 to 15 - your homework for today (Wednesday) was nos 1 to 7).
2. Do the questions on page 34 / 35
Both of the above are to be completed for Friday 3rd December.
Keep safe and warm
