The figure below shows three cylindrical copper conductors along with their face areas and lengths. Compare the resistance and resistivity of the three conductors.Justify your answer.
Answers
Answer:
Figure.3
Explanation:
This traditional view is still used in elementary treatments of geometry, but the advanced mathematical viewpoint has shifted to the infinite curvilinear surface and this is how a cylinder is now defined in various modern branches of geometry and topology.
The shift in the basic meaning (solid versus surface) has created some ambiguity with terminology. It is generally hoped that context makes the meaning clear. Both points of view are typically presented and distinguished by referring to solid cylinders and cylindrical surfaces, but in the literature the unadorned term cylinder could refer to either of these or to an even more specialized object, the right circular cylinder.
Answer:
resistance: b>a>c
resistivity : same for all as made of same metal
Explanation:
resistance depends upon length and and crossectional area of conductor.
If length increases then resistance increases.
if area of cross section increases resistance decreases.
