What is the unit of the physical quantity “Inductance”? A. Weber B. Farad C. Henry D. Tesla

Weber
Farad
Henry
Tesla

The correct answer is C. Henry.

Inductance is the property of an electric circuit that opposes any change in current through it. It is measured in henries (H), after Joseph Henry, who discovered electromagnetic induction in 1831.

A weber (Wb) is the unit of magnetic flux. It is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of one volt if it were reduced to zero at a uniform rate in one second.

A farad (F) is the unit of capacitance. It is the capacitance of a capacitor that, when charged to a potential difference of one volt, has a charge of one coulomb.

A tesla (T) is the unit of magnetic field strength. It is the magnetic field strength that, at a distance of one meter from a straight conductor carrying a current of one ampere, would produce a force of one newton per meter of length on a conductor carrying a current of one ampere in the same direction.
