I have a quention for problem 5.16.
You can refer problem 4.20, 4.41 to solve the 5.16. So I
attached the information for the problem solving including some
table of ASCR.
But the problem is the last picture I attached. I don't know
why 0.0969 (resistance) is have to divided by 3.
Please give me very detailed and easy explation.
