R = V/I = pL/A,,    so,if keeping V cons. I is doubled, L and A remains the same, so p should change,, but it doesnt changes.. WHY,?? PLS EXPLAIN IN REFERNCE TO THIS STATEMENT!!!

p Depends only upon The Nature of Material it does not depends upon its Geomety.

 

Please Don't Get Confuse , There is Something Wrong with This Question if i is doubles , V will Also get doubled as V Is Proportional to I.

hi,

ohms law states that potential difference across a conductor is directly proportional to the current provided the temperature remains constant.so if current doubles (for given conditions)  v cannot remain constant.....

 

plzzzz approve!!!!!!!!!!!!!!!!

							p(rho) depends on the material. If we change the material of the resistor then only p(rho) can be changed.
Since I is directly proportional to V. If I is doubled then V also gets doubled, it can't remain unchanged.
