Homework Help Overview

The discussion revolves around an electric circuits problem involving the brightness of lamps in a circuit diagram. The original poster is particularly focused on understanding the behavior of specific lamps (c, d, g, and h) in relation to an original lamp.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to analyze the circuit by considering the brightness of lamps and suggests that redrawing the circuit might help. Participants question the voltage across lamp d and explore the implications of removing lamps g and h from the circuit.

Discussion Status

Participants are engaged in exploring the problem, with some guidance provided on considering the voltage across lamp d. There is an emphasis on the importance of the original poster's reasoning process regarding lamps g and h, indicating a productive direction in the discussion.

Contextual Notes

The original poster expresses difficulty in redrawing the circuit and is seeking clarification on the relationships between the lamps, which may indicate constraints in their understanding or available resources.

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...?
