Lesson Plan

4.4 and 5.4 Components and Characteristics

 

Who am I laminated card sort, to work out which symbols match up with which functionality.  Once done, they need to draw thea table - component/symbol/purpose and use the textbook to flesh out.  They dont like doing this as a cut and stick ....

 

Notes on characterising a component by looking at how the current and potential difference are related.  PPT to help go through this before writing notes. Leads on to conductance graphs and many examples of. How does R vary with T, what is the temp coefficient and some numerical examples.

 

They should see a diode.  Apply an increasing voltage and show how there is a threshold for the LED and a directional quality.

 

Takes about 30 minutes.  Chapter 4.4 questions.
