Electrical Engineering XYZ Multiple Choice Question on Conductivity is reciprocal of
Conductivity is reciprocal of
- Resistance
- Current density
- Resistivity
- None of these
Correct answer: 3. Resistivity
Explanation:
Resistivity (ρ) is an intrinsic property of a material that quantifies how strongly it resists the flow of electric current. It is the reciprocal of conductivity (σ)
Mathematically:
ρ = 1/σ
