Q. If $L$ denotes the inductance of an inductor through which a current $I$ is flowing, then the dimensional formula of $LI^{2}$ is
A) $\lbrack MLT^{- 2}\rbrack$
B) $\lbrack ML^{2}T^{- 2}\rbrack$
C) $\lbrack M^{2}L^{2}T^{- 2}\rbrack$
D) Not expressible in terms of $M,L,T$
Explanation
Both $\frac{1}{2}LI^{2}$ and $\frac{1}{2}CV^{2}$ represent energy.
