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.

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

Mrs M :-)
