Electric circuits problem (diagrams included)

SUMMARY

The discussion focuses on solving an electric circuits homework problem involving the brightness of lamps in a circuit diagram. The user seeks assistance specifically with lamps c&d and g&h, indicating that redrawing the circuit may help in understanding the relationships. A key insight provided is that if lamp c and its mirror image have normal brightness, then the voltage across lamp d is 0V, resulting in lamp d being off. Participants encourage deeper analysis of the circuit by considering hypothetical scenarios regarding lamps g and h.

PREREQUISITES
  • Basic understanding of electric circuits and components
  • Familiarity with voltage concepts and their effects on lamp brightness
  • Ability to interpret circuit diagrams
  • Knowledge of series and parallel circuit configurations
NEXT STEPS
  • Study the principles of series and parallel circuits in-depth
  • Learn how to calculate voltage drops across components in a circuit
  • Practice redrawing complex circuit diagrams for clarity
  • Explore the concept of symmetry in electric circuits and its implications on component behavior
USEFUL FOR

Students studying electrical engineering, educators teaching circuit analysis, and anyone looking to improve their problem-solving skills in electric circuits.

Homework Statement

Basically I need to find the brightness of the labelled lamps relative to the original lamp.

It is lamps c&d and g&h which are causing me the most trouble. Can anyone tell me what I should be looking for? I think redrawing the curcuit would be a good idea but I can't even do that.


Any help would be much appreciated.

Hint on c&d -- if c and its mirror image have normal brightness, what is the voltage across d?
 
Oh yeah it would be 0v so the bulb d is off


Any ideas on g and h?

Sure. But we want to hear your thinking about it -- that's what's important.

Poke at the problem some. What if g and its twin weren't there? What if h wasn't there? What are your thoughts about how to combine those two situations...?
