SUMMARY

The discussion focuses on solving a circuit problem involving three currents (I1, I2, I3) and the terminal voltage of a 6.0-V battery, considering an internal resistance of 1.0 Ohm for each battery. Participants emphasize the application of Kirchhoff's Loop Rule and Junction Rule to derive the necessary equations. The voltage drop across the internal resistance is crucial for calculating the terminal voltage, which is obtained by subtracting this drop from the battery's nominal voltage.

Hi knobles8179! Welcome to PF! :smile:

(btw, two h's in Kirchhoff! :wink:)

That's right … do loop equations for any two of the three loops, and a junction equation, and find the voltage drop across the "r" resistance (which i assume is intended to represent the internal resistance of the 6V battery), and subtract it from the 6V. :smile:
