The unit of capacitance is the farad. Which option correctly names the unit?

The unit of capacitance is the farad. Which option correctly names the unit?

• A. Henry
• B. Siemens
• C. Farad
• D. Volt

Answer: (C)

Capacitance is defined as charge per volt, so its unit is coulombs per volt. In SI, that unit is called the farad (symbol F). One farad means one coulomb of charge stored per volt of potential difference. The other options belong to different quantities: Henry is inductance, Siemens is conductance, and Volt is electric potential difference. So the unit for capacitance is the farad.
