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.
If you want to read the text along the x-axis, just click on thisÂ pdf version of the traffic light chart. You will be able to zoom in using Acrobat’s zoom feature and read the full text label for each of the criteria (get Adobe Acrobat Reader here).
I will address the topics attracting the highest red scores first, so we will start with “know that the declared value of an alternating voltage is less than its peak value”. We will start a lesson with this topic in the next week.
Please bring back the problem booklet and your completed homework on Tuesday 29/08.
We looked at the relationship between current, voltage and power in our last lesson. The good people at howstuffworks.com have an excellent page that summarises this topic – click here to check it out.
We had some discussion about the use of voltmeters and ammeters this week. I found this site tonight. It has information on several types of meter and is worth a look.
We’ve nearly finished the first week of term. Hopefully your timetables are all sorted and you are starting to get back into the learning routine again 😉
Feel free to use this site to remind yourself what we have worked on during the week, last week or last month as we work through the Standard Grade course. There are categories down the side menu to guide you to the correct course unit, along with links to other sites you might find useful. I will add updates as we cover new topics. You can ask questions or start discussion by posting comments. (Rude comments will be removed!)
