Resistance and Radii Relationship

AI Thread Summary
The resistance of wire A is stated to be four times that of wire B, leading to a discussion about calculating the ratio of their radii. It is clarified that if both wires have the same cross-sectional area, their radii must also be equal, resulting in a ratio of 1:1. Participants emphasize the need for accurate problem details and suggest that the original question may have been misinterpreted. The importance of providing complete information for a proper solution is highlighted. Ultimately, the conclusion is that the radii ratio is fixed at 1:1 if the wires share the same cross-sectional area.

Are the wires the same length?

Are they made of the same material?
 
the wires have the same material and same cross-sectional area

Are you sure about this?
 
Yaaa...sure..!

If they have the same cross-sectional area then they have the same radii and the ratio is fixed at 1:1. Any other information or details would be irrelevant. It therefore seems likely that you have either misinterpreted the question or are not providing the true problem statement for reasons we can only guess at.
