Q. The dimensions of emf in $MKS$ is
A) $ML^{- 1}T^{- 2}Q^{- 2}$
B) $ML^{2}T^{- 2}Q^{- 2}$
C) $MLT^{- 2}Q^{- 1}$
D) $ML^{2}T^{- 2}Q^{- 1}$
Explanation
$e = L\frac{di}{dt}\ \Rightarrow \lbrack e\rbrack = \lbrack ML^{2}T^{- 2}A^{- 2}\rbrack\left\lbrack \frac{A}{T} \right\rbrack$ $\lbrack e\rbrack = \left\lbrack \frac{ML^{2}T^{- 2}}{AT} \right\rbrack = \lbrack ML^{2}T^{- 2}Q^{- 1}\rbrack$
