Question

Dimension of electric current is

• A. $\lbrack M^{0}L^{0}T^{- 1}Q\rbrack$
• B. $\lbrack ML^{2}T^{- 1}Q\rbrack$
• C. $\lbrack M^{2}LT^{- 1}Q\rbrack$
• D. $\lbrack M^{2}L^{2}T^{- 1}Q\rbrack$

Answer 1

Answer: (A)

$\lbrack M^{0}L^{0}T^{- 1}Q\rbrack$

Answer 2

$I = \frac{Q}{t} = \frac{\lbrack Q\rbrack}{\lbrack T\rbrack} = \lbrack M^{0}L^{0}T^{- 1}Q\rbrack$
