Wikipedia has a good description of how a ring circuit is used in home wiring. The diagram below is neater than the one I drew on my board in class. You can click on it to view a larger version of the drawing.
I have uploaded a set of notes on the Using Electricity unit. Please click on the download link below and save a copy on your computer at home. I would like everyone to read up to the end of page 19. This will cover everything that we have looked at so far on this topic.
Please try to answer as many of the questions in these notes as you can, either by printing out the pages and writing in the spaces or using your Physics jotter.
You may leave a comment if you get stuck with anything and I will try to help.
If you can’t get to school due to the snow, here is some physics work so that you can keep up with the course.
We started looking at Ohm’s Law last week. Go to the HelpMyPhysics site and try the Ohm’s Law activities there. I have also uploaded some additional problems taken from our classroom booklets. Click on the download link below to get your copy. You can leave a comment here if you get stuck or want to ask a question.
Due to problems with school transport, I have moved the tests scheduled for today and tomorrow. The general test will now be tomorrow (Tuesday 12th Jan) period 1, with the credit test on Thursday14th Jan (period 6).
The calendar on the right has been updated to show these changes.
You can download the HW by clicking on the download link or you can get it through iTunes by following the S Grade Podcast link in the sidebar. Please do this exercise in your new homework jotter and hand it in to me on Thursday 19th September. Thanks.
Here is the video we recorded yesterday. I have trimmed the film down to 3 minutes in length so we can focus on the more essential aspects of the “hoover autopsy”. You’ll notice that I have removed all of the conversations we had while the hoover was being filmed.
Your job is to tell me something about the things in the video.
It might be
something about electricity you remembered from before the holidays
maybe you learned something as we took the hoover apart?
sharing information about something you can see in the video
a calculation based on information you spotted in the video.
There are a few ways you can do this.
I uploaded the video to a site called Voicethread. This site allows you to record voice or video clips as well as typing a comment. It will also let you doodle on the video at any point if you need to highlight something. Click on the Voicethread video where it says comment to share something you learned or remembered during the lesson or from the video.
If you choose to leave a comment on Voicethread, use only your 1st name when you sign up to their site and pick a picture or cartoon for your image. Don’t go uploading a photo of yourself – see how I chose to use a picture of a Highland cow instead of my own photo.
The other way to make your contribution is to add a comment straight on to this blog. You can do this by using the comment link next to this blog post. Your comment will go into a queue for me to check it is not spam, so don’t expect it to go on to the blog straight away.
If you want to keep a copy of the video, feel free to click on the download link below.
I’ve had an email from Yenka to say that they are now offering many of their products for home use – free of charge! I think Yenka is the new name for Crocodile Clips, the company who made Crocodile Physics and Crocodile Technology. Their software allows you to create your own experiments to learn about
I’ve uploaded a set of summary notes that you might find useful as you prepare for the end of unit tests on Using Electricity. Download the pdf file using the link below.
I was going to show you all this youtube video on how to make your own electric motor home but the school was closed due to bad weather. I also found this diagram showing the parts of a dc motor.
