I've attached a schematic copied from exercise 1.29 "Art Of Electronics" 2nd Edition. The problem is to create a 10mA trickle charge for the battery. The answer is to use the resistor shown in my schematic (the exercise does not show the resistor.) I have an answer page that I found from the Harvard syllabus and it shows the resistor being 300Ω?! By my interpretation of Ohm's law the resistor value should be 1500Ω (1.5kΩ.)
What am I missing?
p.s.
There were no values for the diodes in the book. I just used what seemed reasonable from the Eagle library.
