Q. The dimensional formula of self-inductance is
A) [$MLT^{- 2}\$]
B) [$ML^{2}T^{- 1}A^{- 2}$]
C) [$ML^{2}T^{- 2}A^{- 2}$]
D) [$ML^{2}T^{- 2}A^{- 1}$]
Explanation
Energy $E = \frac{1}{2}LI^{2} \Rightarrow \lbrack L\rbrack = \frac{\lbrack E\rbrack}{\lbrack I\rbrack^{2}} = \frac{\lbrack ML^{2}T^{- 2}\rbrack}{\lbrack A^{2}\rbrack} = \lbrack ML^{2}T^{- 2}A^{- 2}\rbrack$
