Question

Error Analysis .The solution shown for the equation is incorrect. What is the correct solution? What is the error?

a. -2(3-1) = 10
b. -6-2r = 10
c. - 2r = 16
d. r= -8

Answer 1

The correct solution is b. -6-2r = 10. The error in the given solution is that the equation is not properly balanced. To balance it, the measured current for R3 should be -6 instead of -2r.

Step-by-step explanation:

The correct solution is b. -6-2r = 10. The error in the given solution is that the equation is not properly balanced. To balance it, the measured current for R3 should be -6 instead of -2r. Therefore, the correct equation should be -6-2r = 10.
