- Homework Statement
- When the switch is closed, is the brightness of bulb A greater than, less than, or equal to the brightness of bulb B? Why?
When the switch is closed, is the current through battery X greater than, less than, or equal to the current through battery Y? Why?
- Relevant Equations
- I do not know the equations.
As demonstrated by the figure, bulb A and bulb are in a parallel circuit whose batteries are ideal and identical. I am asking for assistance to see where I am going wrong in my approach and how to better understand and figure out the question!
1. If the switch was closed, the brightness of bulb A would be less than the brightness of bulb B due to the potential difference as a result of the pathway. However, I do not know if this is correct or if there was another reason. I was thinking that because A does not have a resistor that it would have potential flowing more freely.
2. I am not sure about this question, but I am assuming that it bulb A is less bright than bulb b, that would mean that battery X is generating a greater than battery Y. THIS IS THE FIGURE FOR THE PROBLEM. (The lightbulbs are identical, and the batteries are ideal and identical.)
