[@shayanay6688]

Sir non metals main resistance decrease hoti hai with increase in temperature why?

[@afnanbakht]

Bcs in non-metals there are no free electrons..and with the rise in tempereture some of the bound electrons gets free and gets available for conduction..so its resistance decreases...thats why...but in metals free electrons r already there,so increasing there tempereture increases their collisions and hence increases resistance

Yes.......I can explain .....Q k vector law oF division nahi hai

[@ruqiazuhra6679]

Sir jb alpha ki value large hogi to ye material conductor hoga?

[@afnanbakht]

Conductor ka hona ya na hona depend kerta hai ke wheather it allows the flow of charges through it or not, even at small temperature if its resistance gets very high(Alpha value is large) then still conductor allow the flow of charges..but allow less...so u can say now it is acting like a bad conductor..but still a conductor..

[@ruqiazuhra6679]

@@afnanbakht sir conductor me temperature increase krne se resistance must increase hogi.....ya to boht zyada increase hogi ya km magar increase hi hogi?

[@afnanbakht]

Yes..for conductor increase is must...

Please sir reply I request you sir ap ne jo 2 conductor suppose kiye or pir ap ne screen per a bhi dikaya key let one is copper and other is iron To sir kia copper main tori si temperature deaney resistance bout ziada hosakti hai yaa iron Orr ziada temperature per kis ki resistance per ziada perq perney ka chance nahi hai copper or iron And why?? and why?? and why???

Sir what is fractional change in resistance🤔

[@afnanbakht]

Change in R (deltaR) divided by initial Resistance..its kind of like strain for resistance..change divided by original
