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???
Sir Ohm's law ka Constant 1/R hta ha ... Matlb Conductance ( reciprocal of Resistance hua ) to ham commonly Ohm's Law ka constant 'G' sy kiu represent nai karty ???
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
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

sir area = πr2
agr length inc. ho 2 times tou area kam hoga
area kam hoga tou radius b kam hoga
suppose area 2 time kmm tou radius b 2 time km tou r2/2 ka square lein ge tou r2/4 aye ga or area 4 time kmm hoga orr 4 upar jae ga tou 2L se multiply ho kr 8L ho jae ga tou resistance 8 times ni brhe gi(MCQ #4)
radius two time ni Four time ho ga r ka square h

Sr zaroori h red wire hogi to current km flow kare gi and black hogi to current bhi zyada hogi due to length?
No clr se aisa ni ho ga

Our sir ye questions paper k lyhaz sy long ma karna ha ya short ma
vid me btaya hwa h,puri vid dekhti na ap...long question hai
Sir mcqs no 1 me agr resistivity k jaga resistance mangy to resistance two time increase hoga naa koyi k length double hai
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
length me change any se area p farq pary ga...mtlb jb stretched kry gy
Me nay theek kaha na
