I happened to be looking through one of my electronics books the other day and found the attached circuit. Looks wrong to me, so I went to a popular beginner electronics site and found two similar circuits:
All three of these seem wrong to me. How can there be any collector current in the PNP without a bipolar supply? Am I missing something?
The two images from www.electronics-tutorials.ws might just be mislabeled. But the one from my book is clearly suggesting it as an alternative to having a bipolar supply. Where is the PNP collector current coming from?
