What is the unit of specific resistance?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Ohm meter.
The unit of specific resistance, also known as resistivity, is the ohm-meter (Ω·m) in the International System of Units (SI). It represents the resistance offered by a material to the flow of electric current through a conductor of unit length and unit cross-sectional area. A material with higher resistivity resists current flow more. Resistivity depends on the material's nature and temperature and is a key factor in determining its electrical conductivity.
