When a wire is stretched to double of its length then its resistance?
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.
How will resistivity change for a wire stretched to thrice its length?
Solution. (i) Since resistivity depends on the nature of the material of wire and is independent of dimensions of wire, so the resistivity remains unchanged.
What happens to resistivity of A wire if it is stretched?
Answer: The Resistivity of the wire will not change with the change in length. Resistivity is a property of the wire, it doesn’t depend upon it’s length or cross-sectional area.
What happens to the resistivity of a wire if it is stretched?
Resistivity of a material does not change with dimensions. It depends on material and temperature. Hence, by stretching a wire, there will be no effect on its resistivity. It will remain same.
What is the other name of resistivity?
Resistivity may also be referred to as the specific electrical resistance, or volume resistivity, although these terms are less widely used. Although materials resist the flow of electrical current, some are better at conducting it than others.
What is the new resistivity of a 10 ohm meter wire?
A wire of resistivity 10 ohm meter is stretched to double its length. What is its new resistivity? – Quora A wire of resistivity 10 ohm meter is stretched to double its length.
What happens when a wire of resistance 1 ohm is stretched?
A wire of resistance 1 ohm is stretched to double its length. What is the new resistance? Given: a wire of resistance 1Ω is stretched to double its length. Now after the act of stretching the volume remains constant. Was this answer helpful?
