Finding the terminal voltage across 16V and 8V batteries?

Click For Summary
SUMMARY

The discussion focuses on calculating the terminal voltage across a 16V battery and an 8V battery in a circuit. The user initially calculated the total current as 5A but struggled with the subsequent steps, incorrectly subtracting voltages due to internal resistance and other resistors. The need for a circuit diagram was highlighted to better assess the user's approach and logic in solving the problem.

PREREQUISITES
  • Understanding of Ohm's Law (V=IR)
  • Knowledge of internal resistance in batteries
  • Familiarity with basic circuit analysis techniques
  • Ability to interpret circuit diagrams
NEXT STEPS
  • Study the impact of internal resistance on battery performance
  • Learn how to draw and analyze circuit diagrams
  • Explore series and parallel circuits in electrical engineering
  • Review techniques for calculating voltage drops in circuits
USEFUL FOR

Students studying electrical engineering, physics enthusiasts, and anyone looking to improve their circuit analysis skills.

Homework Statement



Find the terminal voltage across the 16-V battery and 8-V battery.

Homework Equations



V=IR

The Attempt at a Solution



I calculated the total current of the circuit to be 5-A, but after that I'm stuck. What I did (and it was wrong) was simply use the voltage of the battery and subtracted the voltage produced by internal resistance as well as the other resistors.

Any guidance would be much appreciated.

Can you provide a circuit diagram? It's hard to judge your logic and conclusions without seeing the actual problem.
