1 henry is equal to-
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 1 Wb A−1
Self-inductance is the magnetic flux linked with a coil per unit current through it.
\( \displaystyle \Phi = LI \)
\( \displaystyle L = \frac{\Phi}{I} \)
\( \displaystyle 1\,\mathrm{H} = \frac{1\,\mathrm{Wb}}{1\,\mathrm{A}} = 1\,\mathrm{Wb\,A^{-1}} \)
NCERT (2026-27):
Inductance – “… Inductance is a scalar quantity. It has the dimensions of \( [\mathrm{M\,L^{2}\,T^{-2}\,A^{-2}}] \) given by the dimensions of flux divided by the dimensions of current. The SI unit of inductance is henry and is denoted by H.”
