Series and Parallel Circuit Problem

Click For Summary
SUMMARY

The discussion focuses on calculating the battery voltage in a series circuit consisting of a 54 ohm resistor and a 23 ohm resistor, with a current of 0.13 A flowing through the circuit. Using Kirchhoff's voltage law and Ohm's law (V = IR), the voltage across each resistor was determined, leading to the correct calculation of the total battery voltage. The application of these fundamental electrical principles ensured accurate results.

PREREQUISITES
  • Understanding of Ohm's Law (V = IR)
  • Familiarity with Kirchhoff's Voltage Law
  • Basic knowledge of series circuits
  • Ability to perform calculations with resistors in series
NEXT STEPS
  • Study Kirchhoff's Laws in more depth
  • Learn about series and parallel circuit configurations
  • Explore advanced circuit analysis techniques
  • Investigate the impact of resistor values on total circuit voltage
USEFUL FOR

Electrical engineering students, hobbyists working with circuits, and anyone looking to deepen their understanding of series circuit analysis and voltage calculations.

I have a problem that I'm working on, not sure what equation to use for this:

The current in a 54 ohm resistor is 0.13 A. This resistor is in series with a 23 ohm resistor, and the series combination is connected across a battery. What is the battery voltage?
 
Physics news on Phys.org
Use Kirkhoff's voltage law (loop: resistor1 - resistor2 - battery) and Ohm's law (V = IR).
 
Ok, I got the answer correct. Thanks for your help!
