Question

Which of the following has low resistivity ?
1.Glass
2.Diamonf
3.Nichrome
4. Ebonite

Answer 1

Resistivity refers to a material's resisting power to the flow of electric current through it.

Resistivity is also the opposite of conductivity and the unit it is measured in is ohm m.

Here, option (3) is the correct answer.

Nichrome has the lowest amount of resistivity at 10^-6 ohm m as compared to the other elements.

Answer 2

Answer:

Nichrome has low resistivity.

Explanation:

Resistivity expresses the resistance in the flow of electricity from the substance. In other words we can say that as the resistivity increases, it becomes difficult to flow the electricity.

Here in the given options, glass, diamond and ebonite are insulator means cannot flow the electricity due to high resistance whereas Nichrome has low resistivity as it allows the flow of current through it.
