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