Question

List two distinguishing features between the resistance and resistivity of a conductor
wire is stretched so that its length becomes 6/5 times of its original length. If its original
resistance is 25 ohm, find its new resistivity.​

Answer 1

Answer:

resistance depends on length of conductor

but resistivity doesn't depends on length

unit of resistance is ohm

unit of resistivity is ohm m

length become 6/5 times then area of Cross section is 6/5 times decrease

if resistance is 25 ohm then new resistance is

30 ohm
