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.

Friday 3rd 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

Resistance in parallel.....not quite as straight forward as resistance in series....take care when you are doing these questions....so easy to forget the last step.

Some examples will have helped...

You handled the experiments well...we shall talk more about potential dividers next lesson...

Homework for next lesson..1st December is page 28 /29 nos 1 to 7

Have a good weekend

NAB ..well done to those who passed and 'we will work together' to those who failed.

Experiment to find resistance and series and parallel went well....more on how to calculate it in parallel next lesson.

Homework for Friday is page 26 nos 1,2,5,8,9

Any questions you know where to come

Monday 22nd November 2010

NAB over and done with for most of you.....date set for those who did not sit as Thursday 2nd December - lunch cards available....as the test will start at 12.45

Brief review of what we had done to date in electricity. I was very impressed with the amount you remembered. Well done...

Homework for next lesson (Wednesday) is to make sure you have all the notes up to and including page 21 copied up and to do the following questions....
page 7 nos 4,6,8
page 18 nos 1,2,3
page 22 nos 2,4,6

NAB results available from me in the morning
