SUMMARY

The discussion focuses on calculating currents in a bridge circuit, specifically using the values I=6A, I2=4A, and I3=0. The calculated values are I1=2A, I4=4A, and I5=2A. The logic applied is correct: I1 is derived from the difference between I and I2, while I4 is the sum of I2 and I3, and I5 corresponds to I1. The conclusions drawn are accurate and confirm the calculations presented.

PREREQUISITES
  • Understanding of Kirchhoff's Current Law (KCL)
  • Basic knowledge of electrical circuit theory
  • Familiarity with bridge circuit configurations
  • Ability to perform basic algebraic calculations
NEXT STEPS

Referring to the bridge circuit of fig P90, if I=6A, I2=4A, and I3 = 0, find I1, I4, and I5.

I did,
I1=2A
I4=4A
I5=2A

My logic being, since I is 6A, and I2 is 4A, I1 must be the difference, 2A. since I4 is coming from I2 and I3 it should be the sum, (0 + 4A = 4A). and I thought because I5 is coming from I1, it must be 2A.

Is this right?
Thanks for any help!
