- SI unit of conductance is ohm-1 (mho) or ohm per meter or seimens.
- Here given ohm meter which is wrong
CONCEPT:
- Electrical conductance (K): The reciprocal of electrical resistance is called conductance.
- It is a measure of how easily current can flow through a material.
- Its SI unit is Siemens.
Electrical conductance (K) = 1/R
- Electrical resistance (R): The electrical resistance of a material refers to its opposition to the flow of current.
- Its SI unit is Ohm (Ω).
EXPLANATION:
The SI unit of conductance = 1/ (The SI unit of resistance) = 1/Ω = Ω-1 = Siemens. Hence option 2 is correct.
- Ohm is the SI unit of resistance.
- Ampere is the SI unit of current.
- Ohm-meter is the SI unit of electrical resistivity which is the measure of an object's ability to oppose the flow of current.
