SUMMARY

The forum discussion centers on the analysis of a circuit using Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL). The user correctly calculated the current i2 as 0.8A, while the solution manual incorrectly stated it as 1A. Additionally, the user determined the current i3 to be -2.2A using KCL, confirming that the solution manual's values are incorrect. The consensus among participants is that the user's calculations are accurate and the manual contains errors.

PREREQUISITES
  • Understanding of Kirchhoff's Voltage Law (KVL)
  • Understanding of Kirchhoff's Current Law (KCL)
  • Basic circuit analysis techniques

Homework Statement



Attached the problem


The solution manual got that i2=1A.I got i2=.8A by applying KVL giving me 20/25=.8A. The solution manual is wrong right?

For i3, I got -2.2A by applying KCL.

Right, the solution manual is wrong. Your value for i2 is correct.
