This is a problem from a book that I'm working with. So this would be considered property of the rightful owner with respect to copyright. The book is All New Electronics, by Harry Kybett, Earl Boysen, published by Wiley Publishing. Page 32, question 8.
Attached is a copy of the circuit schematic
The question I'm having a bit of trouble with states.
VS=12V, I=300mA, R1= 50ohms
Find R2= ____, P1= ____
The correct answer according to the text is R2= 200ohms, P1=2.88 W
I have Ohms Law pie chart. But this is just not obvious to me.
How did they extract R2 and P1?
Could somebody step me through the logical approach to this scenario?
Thank you, for any and all help in explaining this to me.
