Question

Which of the following is the SI-derived unit for measuring electric conductance?
1. Tesla
2. Farad
3. Henry
4. Siemens

Answer 1

Correct Answer - Option 4 : Siemens

The correct answer is Siemens.

• Siemens is the SI unit for measuring electric conductance.
• Siemens per unit is the unit of electrical conductivity.
• Mho is also known as siemens.
• The reciprocal of ohm is siemens.
• The reciprocal of resistance is siemens.
• In the 14th general conference on weights and measures, the unit of conductance known as siemens was adopted.
• The unit was named after Earner won Siemens.
• The ratio of current density to the electric field strength gives the value of electrical conductivity.
• If the conductivity of a substance is higher, then the resistance of that substance will be lower and the flow of electric current will be smoother.
• The ability of electrons or charge carriers decides the value of electrical conductivity.

•  Henry is the SI-derived unit of electrical inductance.
•  Farad is the SI-derived unit of electrical capacitance.
• Tesla  is a unit of the magnetic induction.
