Sir! McQ if wire stretched.L=2L then area=length ×width tu area increase ni hona chahye?? Or 2nd possibility wire stretched means nothing added or subtracted (length) Mtlb wire h tu wohi ki wohi na yani kch or add kr k length ni increase ki ossi ko stretch kia tu resistance same ni honi chahye???

[@rajputrao]

AOA dear, You are working very well. But in this topic of resistivity a confusion has been arisen. You have used term m3 for the definition of resistivity, but in sense of volume m3 if we increase the length of wire/conductor and decrease its diameter than ( m3 of metal) could not be used. If I am right than kindly also elaborate it. Best Regards

Sir mcqs no 1 me agr resistivity k jaga resistance mangy to resistance two time increase hoga naa koyi k length double hai

[@moizsaqib7588]

Gg honi to double chahiye kion kah length double hoi hai double to hoi but area may koi change nhi hai change sirf or sirflength hoi hai area us Wakat change hoga jab us ko stretched Kiya jay GA is liyah ap theek kah rahay hain shayad

man tw len phr find kia krna h,agr find resistivity krna h tw phr chaye resistance 2ble kro ya length,resistivity p farq ni parna
