Thank you for your content, Professor Fiore! Commenting on the final circuit. D2 is reverse bias, so relatively no current would go through that loop. 0.7v would be at D2 cathode. D1 is forward bias, so it should drop 0.7v. Knowing that, the 1k resistor should drop 9.3v. Current through that loop should be around 9.3mA.

This is where I'm up to in your notes. I'm enjoying your humour, are you sure that you're not British? :) Electron sized cat-flaps indeed....

What is the criteria for selecting knee voltage in the diode I-V curve?

I've got a quick question now if we got 2 circuits both got the same resistance and battery first one got a silicon diode and the second has a germanuim diode and then we placed a voltmeter on both diodes and showed 0.5 on both of them does that mean the silicon one has a current of zero??? (Since the voltmeter show rms value)
