What will be the resistivity if a wire is cut into half?

The resistivity will remain same since it’s a property of a material,not length. But, the resistance will be half of initial resistance of the wire.

What will happen to the resistivity of the conductor if it is cut into three parts?

After cutting it into 3 equal parts, each part will have resistance R/3. SERIES COMBINATION: In series combination, equivalent resistance is the sum of individual resistances.

Is there any change in the resistivity of a metal If a wire made of it is cut into pieces?

Answer: The resistivity of the two parts will be same. 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.

What will be the change in the resistivity of a resistance wire when its length is doubled by stretching it uniformly?

Complete step-by-step answer: (d) Resistivity of wire remains constant. As the length of wire gets doubled, the cross-sectional area will become half of its previous value because volume of wire remains constant. Hence, we can see that the new resistance is four times the previous resistance.

What will be the change in resistivity?

Resistivity of a conductor such as wire will increase by nine times when it is stretched by three times. It is directly proportional to the length and inversely proportional to diameter. When the conductor is stretched, the diameter decreases and the length increase increasing resistivity.

What changes do you observe in resistance and resistivity?

Explanation ⇒ Resistivity being an property of the matter do not changes either its length or area of cross section changes. Now, As per as the question, A wire having Resistance ‘r’ is break into 2 equal parts, then, Resistance will becomes half. Thus, Resistivity Initial = Resistivity final.

What is its new resistivity?

Answer: The new resistivity of the material of the wire is . The resistance of the wire is equal to the product of resistivity of the material and length of the wire divided by the area of cross section.
