A wire of length /, made of material resistivity (X) is cut into two equal parts . The resistivity of the two parts are equal to, x X/2 2X 4X
Answers
Answer:
Explanation:
The resistivity of the two parts will be same.
Length = l
Resistivity = ρ
We know that,
Relation of resistivity and resistance
ρl/a
Where, = resistivity of wire
R = resistance
A = area of wire
l = length of wire
If we cut the wire into two equal parts then the length will be change of the wire but will not change the resistivity of the wire. Because resistivity depends upon the material of the wire.
Hence, The resistivity of the two parts will be same.
