The SI unit of electrical conductance is ________.

Mistake Points

• 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.
