Question

State whether the following statement is True or False.

Siemen is the SI unit of resistivity.

Answer 1

This statement is false.

Explanation:

• Siemen (also called mho, Ω⁻¹) is the unit of conductance, which is the reciprocal of resistance.
• Resistivity (specific resistance) is given by ρ = RA/L, so its SI unit is ohm-metre (Ω m).
• The correct fact is that the SI unit of resistivity is ohm-metre, while siemen is the unit of conductance.
