Whose SI unit is Farad? 

The correct answer is Capacitance.

Key Points

• Capacitance:-
  • It is the ability of a body to store an electric charge.
  • It is measured in farads (F). (Hence Option 2 is correct)
  • 1 farad is equal to the amount of charge required to raise the potential difference between two conductors by 1 volt.
  • The formula for capacitance is C = εA/d. Here,
    C is the capacitance in farads
    ε is the permittivity of the dielectric material
    A is the area of the plates in square meters
    d is the distance between the plates in meters

Additional Information

• Magnetic flux:-
  • It is the amount of magnetic field lines passing through a surface.
  • It is measured in Webers (Wb).
  • The symbol for magnetic flux is Φ.
• Inductance:-
  • It is the property of a coil that opposes changes in current flowing through it.
  • It is measured in henries (H).
  • The symbol for inductance is L.
• Resistance:-
  • It is the property of a material that opposes the flow of electric current.
  • It is measured in ohms (Ω).
  • The symbol for resistance is R.
